Epic Games Launcher crashes - Log File Error: "Passthrough is not supported, GL is disabled."

General Feedback & Requests
1

First, I start by stating some specs about my computer: my PC laptop is x64 bit Windows 10, its GPU is NVIDIA GeForce RTX 2060 (6 GB).

Second, I’m not sure if this is the correct place to write about problems with the Epic Games Launcher. Anyway, I’ll explain this issue here.

Version 20.1.2-55517306+++UE5+Release-Distro-5.5 of the Epic Games Launcher gives me these same problems that I had encountered in versions 20.1.1-55368482+++UE5+Release-Distro-5.5 and 20.1.0-55101334+++UE5+Dev-Distro-5.5.

I) I can only add items to the Download List’s queue.

II) cannot do the following in version:

  1. Cannot change the order of the items in the Download List’s queue.

  2. Cannot cancel or pause items in the Download List’s queue.

  3. Cannot download and install any video games from the Epic Games Store.

  4. Cannot download and install anything from My Fab Library.

  5. Cannot install Unreal Engine 5.8.

  6. Cannot uninstall a plugin from a previous version of Unreal Engine 5 that is installed in my computer.

III) All of the uninstalled video games in my Epic Games Store’s Library are labeled as unavailable. I started to notice this problem in version 20.1.2-55517306+++UE5+Release-Distro-5.5 of the Epic Games Launcher.

When I am in the Library tab of the Unreal Engine section of the Epic Games Launcher, the launcher crashes as soon as it finished revealing all the items in My Fab Library.

The red debug text on top of the Epic Games Launcher states, “EOSH OFF (ResetFailed)”.

In the middle of the launcher’s screen is a pop-up window entitled, “Epic Online Services Unavailable”. The body of this pop-up window states, "Epic Online Services is currently unavailable, which is preventing the Epic Games Launcher from working correctly.

Please click ‘Restart’ below to restart the Launcher and apply the required update.

For more information, please visit our support article."

Also, the launcher’s cef3.log file keeps writing this error: ERROR:gpu_init.cc(426)] Passthrough is not supported, GL is disabled.

I tried many suggestions for fixes that were given to me by an Epic Support Assistant chat-bot in the Epic Games website. Such as,

  • Uninstalling and reinstalling Epic Games Launcher and Epic Online Services.
  • Deleting the webcache folders in AppData\Local\EpicGamesLauncher\Saved folder.
  • Made sure that I have the latest Windows 10 updates installed.
  • Installing the latest Studio Driver for my NVIDIA graphics card.
  • Switching over to the latest Game Ready Driver for NVIDIA graphics card.
  • Switched the IPv4 and IPv6 of my Wi-Fi connection to a public DNS.
  • Went into NVIDIA Control Panel to include Epic Games Launcher into Manage 3D Settings, and then, set OpenGL rendering GPU to NVIDIA GeForce RTX 2060.

None of these suggestions worked.

This problem started on June/20/2026 with version 20.1.0-55101334+++UE5+Dev-Distro-5.5 of the Epic Games Launcher. I did submit some support tickets with attached log files and screenshots. My feedback from human support agents was to just wait and see if any newer version of the Epic Games Launcher fixes the problem.

Does anyone know how to fix this problem? What does “Passthrough is not supported, GL is disabled” mean? If this is something that could be enabled, then how can I do that? Would doing so fix this problem?

On July 11, 2026, I was able to install Epic Games Launcher v18.12.2 in my old Windows 7 laptop.

This is my first laptop, “HP Pavilion dv7-4285dx Entertainment PC”, its specs include:

  • Windows 7 Home Premium 64-bit
  • Intel Core i5 CPU M 460 @2.53GHz, 2534 Mhz, 2 Core(s), 4 Logical Processor(s)
  • ATI Mobility Radeon HD 6370
  • DirectX 11
  • 6GB Installed RAM

While this version of the launcher was open, its cef3.log file printed this error: “ERROR:gpu_init.cc(426) Passthrough is not supported, GL is disabled”. Even though that happened, there was no red “EOSH OFF (ResetFailed)” debug text on top of the launcher’s screen, followed by the launcher crashing with an “Epic Online Services is currently unavailable” pop-up window. I was able to use this version of the launcher in my old Windows 7 laptop to download and install Unreal Engine v5.8.0 into my external hard disk drive.

I originally blamed my Lenovo Legion laptop’s Epic Games Launcher’s crashes on “ERROR:gpu_init.cc(426) Passthrough is not supported, GL is disabled” in its cef3.log file. However, v18.12.2 of the Epic Games Launcher in my first laptop also printed “ERROR:gpu_init.cc(426) Passthrough is not supported, GL is disabled” in its cef3.log file. Despite that, v18.12.2 of the Epic Games Launcher in my first laptop did not crash like v20.x.x of the Epic Games Launcher in my second laptop, the Lenovo Legion. Like I wrote earlier in this text, Epic Games Launcher v18.12.2 in my first laptop was able to download and install Unreal Engine v5.8.0 in my external hard disk drive’s folder for installed versions of Unreal Engine 4 and Unreal Engine 5.

So, there is no NVIDIA hardware issue in my Lenovo Legion laptop that made its v20.x.x of the Epic Games Launcher crash. There is also no issue in this laptop’s GPU driver that made this laptop’s v20.x.x of the Epic Games Launcher crash. The problem was with the Epic Online Services.

On July 17, 2026, I found a solution that fixed the Epic Games Launcher’s crashing problem in my second laptop. My previous attempts of performing a clean uninstall of the Epic Games Launcher didn’t delete folders “Epic” and “EpicInstallerTemp” in C:\ProgramData. The “Epic” folder must have had faulty Epic Online Services files inside it that kept making the Epic Games Launcher crash. After that, once I had used the Epic Games website’s latest .exe installer for the Epic Games Launcher at that time to reinstall Epic Games Launcher, the launcher started to work properly again.

Here’s the full step-by-step details of my solution:

Solution - How to perform a clean uninstall and reinstall of Epic Games Launcher.

Note: The following was done in a Windows 10 (64-bit) laptop.

Step 1:

Use this tool

MicrosoftProgram_Install_and_Uninstall.meta.diagcab

from

to uninstall the “Epic Games Launcher” and “Epic Online Services”.

Note: I saw that selecting “Epic Games Launcher” in this tool’s uninstall software list also uninstalled and removed “Epic Online Services” from the list when the tool was done with uninstalling Epic Games Launcher.

Step 2:

Note: You will need to enable “Show Hidden Items” in File Explorer.

Step 2.1:

Go to

C:\ProgramData

If you see these folders, delete them:
Epic
EpicInstallerTemp

Step 2.2:

Go to

C:\Program Files

If you see these folders, delete them:
Epic Games

Step 2.3:

Go to

C:\Program Files (x86)

If you see these folders, delete them:
Epic Games

Step 2.4:

Go to

C:\Users[User Name of PC]\AppData\Local

If you see these folders, delete them:
Epic
Epic Games
EpicGamesLauncher

Step 2.5:

Go to

C:\Users[User Name of PC]\AppData\LocalLow

If you see these folders, delete them:
Epic Games Publishing

Step 3:

Restart the PC.

Step 4:

While connected to the internet, use the latest installer from epicgames.com to install the latest version of the Epic Games Launcher.

Step 5:

When the installation of the Epic Games Launcher is done, restart the PC.

Step 6:

Open the Epic Games Launcher, log-in to your Epic Games account, and the launcher should be functioning normally now.

Note: As of writing (7/21/2026), the Epic Games Launcher does not have a simple, user-friendly way of auto-detecting previously installed items, nor entering file path(s) of where your installed items can be found. This means that video games, and versions of Unreal Engine 4/5 and its user’s assets from Fab.com, would need to be re-downloaded and re-installed through the Epic Games Launcher.
