I was just about to make a post asking about the same. Currently working on a demo for our indie game, and after we turned on DX12 (decided to due to nanite and lumen stuff), everytime we want to submit to revision control, our Unreal freezes (happening on multiple pcs). We are running UE 5.3.1. The changes do get sumited like with you guys, but yeah… Unreal just permafreezes. Had no issues with this before we went up to DX12.
Did anyone ever figure out a reasoning or a fix for this?
