UE5 CRASH when it launches

I never successfully opened the editor, it crashes every time.


CrashContext.runtime-xml (90.1 KB) CrashReportClient.ini (112 Bytes) UEMinidump.dmp (903.5 KB) Unreal.log (39.2 KB)

My video card is RTX2060 with updated driver, BTW

I’m having the same problem… the project loads up to above 90% and then crashes. I have Intel Xeon Gold 6134 with 8 cores 32 processors 3.20Ghz 192 GB Ram RTX2080Ti GPU

I got this error when opening the ValleyoftheAcientsproject:

I also can’t run the medium dx12 with this error, I think they some way related (my 5K MST screen?)

Anyone with a R6xxx can run these?ndowsrunnablethread.cpp:86]

I use MSI Afterburner and Riva tuner to monitor hardware stats. Closing them both and restarting UE5 project fixed things for me.

Thanx Belal_Ehmed, now it works :slight_smile:

Glad, that my comment helped you.

I found this out the other day as well. Same resolution worked for me. MSI Afterburner is not compatible with UE5-EA

Starting with no other apps running, still have the crash

I updated my RTX 2080 ti driver with the Nvidia GeForce Experience Game Ready driver v 466.47 and was able to load the Valley of the Ancients project
