My problem was trying to create projects on an external exFAT drive, where the hidden dot files (._*) would crash UE 5.2 on startup. I had to manually clean the project folder with “dot_clean -mn *” (and reclean it on subsequent crashes, and move the project to the APFS system drive to package it). I submitted a bug report.

I’m on a Macbook Air 2020 M1/256/8 and it runs okay (with “Epic” or “High” scalability setting) on the simple projects I’ve made so far.
