Editor stuck compiling shaders

Interesting, is your project setup for raytracing? if so let’s disable it:

For raytracing this will be located here:

[YourProjectFolder]->Config->DefaultEngine.ini

under [/Script/Engine.RendererSettings] you should find r.RayTracing=True , change that to False

Can you also try launching under DX11 or Vulkan by setting this variable? And try again with each and see if it stalls?

DefaultGraphicsRHI=DefaultGraphicsRHI_DX12
                 to
DefaultGraphicsRHI=DefaultGraphicsRHI_DX11
                 or
DefaultGraphicsRHI=DefaultGraphicsRHI_Vulkan
