Crashes with the latest AMD driver, reverted back to 25.8.1 which was recommended in the official website for some reason. Still the getting same error. The only work around I found was to disable raytracing from engine.ini file. Only with RT disabled, can I run the project. But the project I’m working on requires raytracing to be enabled. Help!

Hello there @ByPolarr!

This sounds like a conflict from either your recent driver update/downgrade, or the engine itself. There have been other reports related to AMD and DX12 graphic conflicts. So, we would need to rectify the potential driver issue first.

Since you reverted to a previous driver, step one is to ensure a clean install. Use any driver removal utility (like DDU), then install one of the most stable drivers for this scenario. Following the other threads, the safe bet would be 24.5.1.

Then, to rule out engine problems, go to the Epic Launcher, check the drop-down menu from your build, and click on Verify, which will restore any missing components, and repair any corrupt data.
