Unreal Engine 5.3.1 Constant Crashing

[TheLordYeeteth46]

Ello,

UPDATE 2: 11/1/23 1655 EST
Found a reddit post with similar issue back on 5.1. Issue was related to one of the 3D Settings I had modified globally on NVIDIA Control panel. Set up the per application settings on the only app I modified settings for (Apex), and restored Default Global Settings.

Seems resolved

UPDATE: 11/1/23 1620 EST

Found similar error reports with solutions based around forcing DirectX 11 by modifying the ```../Program Files/Epic Games/UE_5.3/Engine/Config/BaseEngine.ini``` file to include the directive ```DefaultGraphicsRHI=DefaultGraphicsRHI_DX11``` but unfortunately my problem persists. 

Confirmed NVIDIA Drivers and Windows are both up to date as well.

I just installed UE 5.3.1 and was attempting to start going through one of the online tutorials but I’m seeing pretty consistent crashing with the same error, where it’s trying to read at a laughably low mem address and throwing an exception as a result…because well… it shouldn’t be trying to read there XD

I had this issue trying to start up the first project few times (2-3 crashes, wouldn’t even launch).
Was able to get the environment/project to launch after setting the Epic Games Launcher to run as Admin.

I was just generally moving around a bit trying to learn navigation controls and after a few minutes of moving around it crashed again.

Here’s some specs on the machine (Windows X86_65) in question, and the crash report is below. One thing I did do that is a little different is that I installed this on my secondary NVMe drive (Both the engine and my Projects folder)

Windows 10 Home
CPU: AMD Ryzen 7 5800X
GPU: MSI RTX 3070
RAM: 32 GB
C: 1TB NVMe M.2 where my OS is living
D: 2TB NVMe M.2 (Unreal Engine and Project Files were installed here because space)

Unreal Engine Version 5.3.1

Saw some issues open with folks discussing problems when installed on a secondary drive, but nothing that matched up with this weird attempt to read at almost base memory address.

Greetings @TheLordYeeteth46

Welcome to the Unreal Engine forums! I saw that you were having issues with constant crashing. But, you edited it later. Were you able to get this resolved? If not, I’d be happy to look into it and assist further. Let me know! I’ll monitor the thread.

[TheLordYeeteth46]

Yup, there was at least one NVidia control panel setting (I didn’t feel like manually going one by one reverting anything I had globally changed back to default to determine which was which) and rolled them all back default after saving those settings on a per application basis to the respective games that justified the performance tweaks.

Thread can be marked resolved.

Excellent! I’ve actually saw a lot of errors like that resolved with global defaults in the NVIDIA Control Panel oddly enough. I’m happy that you got it fixed and thanks for providing the solution so it can help others in the community who run into this. Have a great day!
