Unreal Editor project loading stuck at 39%

Loading a project in Unreal Editor Version: 4.25.1-13594126+++UE4+Release-4.25 on my computer stuck at 39% when RayTracing is enabled for a project. The Shader Compile Working runs forever on 100% CPU. I have a GTX 1050 Ti GPU and GeForce drivers 446.14 installed.

How-I-fixed-it:
Setting the r.SkinCache.CompileShaders=False in the DefaultEngine.ini (project location\config) made the editor start again.

  1. Thx. I was hopeful this would work in 4.26 as well but now UE requires skincache to be enabled to launch RT projects. It crashes if set to False now. Having to wait many hours for the RT shaders to compile to get past the 39%. Just thought I'd mention it for folks who stumble across this.
