Unreal Crash Error

As far as I know I am on the latest drivers for my version of Debian Sid.

Here is the output of nvidia-smi:

I have checked that all my packages are up to date and I have managed to launch Unreal Engine before on this very machine. I am not sure what else I could try here. I am also certain that I have the latest Vulkan Drivers.

Here is the output of running the engine from the terminal: https://pastebin.com/mMFfYRiP

I would greatly appreciate any assistance from anyone that might know how to solve this. I am not sure what else I should do to troubleshoot this and I have tried all I found online.

I mean I’m no expert on any of these stats. But I noticed your driver version is Linux (correct me if I’m wrong.) Did you download UE using their special Linux download instructions?

If not that it could be a corrupted engine file, in which case you can uninstall and reinstall the engine.

Otherwise maybe rolling back a driver version might help?

All just basic troubleshooting. Sorry I couldn’t be of any more support. Hope it works though!

Yup, as I mentioned I am attempting to run the engine using Linux Debian. I installed the engine by downloaded the precompiled packages that are supplied by Epic Games.

Rolling back to an older version of nvidia drivers is something I don’t want to have to do but I will try it if all else fails.

Reinstalling the version of Unreal that I am using (5.2.1) from the Epics own prebuilt versions of the engine doesn’t seem to work. It just results in the same message.

Thanks for the help anyway.
