Constant Crashes in UE5.6 / UE5.5 / UE5.4

Hello, @AnasMh2025 ,The second log says that the project crashes while pre-processing/compiling shaders.
You can try the following:

  • Moving the Engine to the same physical disk as the project

  • Disable all non-Epic plugins (and also temporarily disable MetaHuman to see if it causes the error).

  • Clearing DerivedDataCache and all Saved/Intermediate folders

  • Disable “Support Compute Skin Cache” Project Settings → Rendering
    (you also have to diable ray tracing )

  • Open the engine using -d3d11
  1. Close the editor.
  2. Search for your uproject file
  3. Right-click - Send to Desktop- (create shortcut).
  4. Right-click the shortcut- Properties.
  5. In Target ,at the end of the quotes, leave a space and type -d3d11 :

Also I found these two posts , It’s not the same log , but they have similar errors , so you could try it and maybe it will work.

From what I’ve researched, I’ve seen that most of the errors happen to people with an Intel i9-14900K and an RTX 4080 or 4090. This post talks about how to fix it by changing the BIOS settings.

Hope it helps ! If nothing works for you, let me know and we’ll see if we can find a solution.
