Describe the bug
While opening the editor, depending on the graphics API it will either crash due to a shader error or produce black lines across the viewport. This is reoccuring, even with a rebuild of both assets & the project itself.

Steps to reproduce
Steps to reproduce the behavior:

  1. Launch editor.
    Expected behavior
    The editor launching without any hiccups in either DX12 or Vulkan set as the renderer API.

Actual behavior
If RHI is set to DX12, it produces a shader error and crashes. If it is Vulkan, the editor viewport loads but has black lines appear across the screen.

Could this be an issue with the version of the Windows SDK being too new or the graphics card not being detected?

This feels like a driver issue. Please attach logs to the ticket as they may provide more leads. It is weird that the AP was unable to create DX12 bytecode for shaders.

Current Windows SDK version is 10.0.22621 with the current AMD driver being 24.3.1 I'll attach logs shortly.

Re-cloning source and rebuilding seemed to fix this somehow, closing.
