Hello again!
That would be a good approach. I would suggest a full uninstall/reinstall of all Epic software:
- First, uninstall the engine, launcher, asset packs, etc
- Next, open the registry directory HKEY_CURRENT_USER\Software\Epic Games\Unreal Engine\Builds, and delete any build entries
- Finally, delete the folders %userprofile%\AppData\Local\UnrealEngine and %userprofile%\AppData\Local\UnrealHeaderTool
- After that, no elements related to UE should be left in your system
- Now, reinstall UE launcher from scratch, and only add the latest version of the engine
- After the process is complete, test compiling shaders again
As alternative solutions, in another thread with a similar problem, it was suggested to alter the priority of the process for shader compilation, reinstalling all elements from Visual Studio 2022, as well as setting an UE exception for antivirus. I would not recommend that last step, though. All details can be found here:
