Hello! I just used Chatgpt and worked!! (Mac version): Good morning! Thanks for sharing the crash screen and explaining the steps. It looks like the Epic Games Launcher crashes after installing the Fab plugin for Cesium, likely due to a plugin compatibility issue or corruption.
Here’s a step-by-step plan to fix it:
Step 1: Manually Remove the Fab Plugin
Unreal plugins can crash the launcher if they’re corrupted or incompatible. Since you mentioned the crash began after installing the Fab plugin:
-
Navigate to your Unreal Engine plugins folder. For example:
/Users/Shared/Epic Games/UE_5.4/Engine/Plugins/Marketplace/
(or whichever version you’re using)
-
Look for any folder named “Fab”, “Cesium”, or anything related to the plugin you installed.
-
Move or delete those plugin folders (move to Desktop if you want a backup).
Step 2: Clear the Epic Games Launcher Cache
Corrupted cache can also prevent the Launcher from starting.
-
Go to:
~/Library/Application Support/Epic/EpicGamesLauncher
-
Delete the entire Saved folder:
EpicGamesLauncher/Saved
-
Optionally, also delete:
~/Library/Logs/EpicGamesLauncher
Step 3: Reinstall the Epic Games Launcher Cleanly
If you’ve only been reinstalling without clearing residual files, try this:
-
Uninstall the Launcher.
-
Then manually delete these residual folders:
~/Library/Application Support/Epic~/Library/Preferences/com.epicgames.EpicGamesLauncher.plist
-
Reboot your system.
-
Download a fresh copy from https://store.epicgames.com and reinstall.
Step 4: Launch Without Plugins (Optional but useful)
If the above doesn’t fix it, try launching Unreal Engine without loading plugins:
-
Open Terminal and run:
open -a "/Applications/Epic Games Launcher.app" --args -SkipBuildPatchPrereq
This sometimes bypasses problematic startup steps.
Optional: Check Logs
The crash reporter mentions logs are included. If needed, you can manually inspect logs here:
~/Library/Logs/Unreal Engine/EpicGamesLauncher.log
If the crash persists after this, feel free to share that log file — I can help analyze it directly.
Let me know if any step works or if you get a different message after trying these!
