hi @jasapetek ,
A common problem with Windows 11

  1. Go into Project Settings type RHI into the search bar and find the box with Direct X 12
  2. select drop-down and select Directx 11 and make sure SM5 shaders are enabled

Restart project

The Windows Drivers for you graphics are not working properly for some unknown reason
See this on how to change RHI outside Unreal Engine

Greetings @jasapetek

Welcome to the Unreal Engine Community Forum. I was going to mention the same things that Jimbo did. However, if that doesn’t resolve the issue, post back here with all of your system specs and I can take a look. I’ll monitor the thread. Thanks!
