When starting up unreal engine it stops at 18% then close

I have the newest Mac with Big Sur 11.2, the Epic Launcher works just fine, but when I try to Launch the actually engine it initializing unit it reaches 35% then closes when no crash log or anything just straight up close and reopens the epic launcher I’m trying to run 4.20 now if that helps. Pls help I need to have this for next class tomorrow and don’t know what to do!

Is there a reason you’re running an old engine version? You’re missing out on thousands of various bug fixes some of which might be related to the issue at hand; not to mention a couple of years worth of features and optimisation…

Is v4.20 a requirement?
