Why Unreal crashes at launch

Hi guys,

I cant use Unreal 5 on my Apple M1 Max (latest Monterey, XCode,VSCode, Rosetta2) Doesnt launch, doesnt create crash report, no error message, nothing. Creates a dock icon for a split second and its gone. I see some other people have asked this over time with no answer, you cant just leave this unsolved, where is the support for this?
It doesnt create crash report/logs every time it crashes, but once when it did it said it cant find libraries in Applications/Unreal/ … but all Unreal files are in Users/Shared/EpicGames/ …

I followed on site install stepts I did not customize or change anything

Regards

HI there,

Sorry not being able to help as I would like but having the very same problem and noticing no report about it, thought it was necessary to underline the problem.
Would be nice to understand. I observe also the nanosecond pop up of an authorisation window… also odd.

All the best.

When I launch UE5 from Launcher does not create a crash report. When started by clicking on UnrealEditor.app creates the following crash report. ( and copying the .dylib files at the expected path does not make it work, it only crashes without report, maybe because of another issue)
