I had the issue that was described in the title, but for 5.0.1. It has taken a lot of time to figure out what is going wrong, and I still don’t quite know what happened, but this has been the only fix that has worked for me.
Description of my problem
The shaders compiling process in the editor or loading the editor (splash screen before opening) would stop compiling and it would eventually crash the editor or my computer if I left it running long enough (~30-45 minutes). Looking through the output logs it appears that the FShader JobCache just stopped receiving information after the first batch and would time out of its process. I don’t know what caused this issue since the engine was working one day and the next it wasn’t.
I will update this post if I ever find the root of the problem.
