Compiling Shaders doesn't work (stuck with no progress)

YES! Thank you! I’ve been struggling with this issue for a while now. (Since 4.19?) I use an Intel Core i9 7980XE at work which has 18 cores - 36 logical and until I found this fix I was stuck only using a couple of cores to compile shaders. Now when I open task manager I see it using all 36 and 100% CPU usage!
