Hello,

Since today UE5 crashes when I click on the player to play on the level. I have the following error message :

But in Simulate mode it plays normally.

Could someone help me?
Thanks a lot

Hi @herve1234!

Here is a thread with the same error code that looks like it has a fix:

DLSS crashes after installing 5.0.2

I hope this solution is what you are looking for!

Hi,
Thank you very much. I found the solution yesterday I simply deactivated the DLSS plugin.
Voilà !

Cheers
