is there something preventing you from telling us which processor you have, and how many cores were being used to compile, and how much ram was in use to compile?
I have i7-10700 and VS was using only 5 cores and 12gb of ram
fwiw, this is not a problem that iāve ever encountered, and iāve done unreal development with native source going back to 2010. likely some configuration error in your VS setup or Unreal configuration (though i canāt think of any unreal ini settings that would affect that, there might beā¦ i know thereās stuff affecting shader compiler and packaging process counts and memory limits)
