Yeah, at least it’s all working via Rosetta. When I first got my 13in MBP when it came out, I couldn’t get it to compile at all.
The editor runs pretty well actually. I did an unreal 5 build, and it was a bit laggy, but if you turn off Lumen and TSR for the viewport renderer, it’s a lot better. It’s definitely usable under Rosetta, but native would surely be a lot better.
