Somebody using Unreal Engine on Mac?

When starting Unreal Engine on macOS 13.2.1 I get many error windows saying something like this: ShaderCompilerWorker returned 2 single jobs, 22 expected.
Then it crashes.
What could be the problem?
How can I fix this?
Is Unreal Engine working on Mac at all?

Greetings @GeneralTom

Welcome to the Unreal Engine Forums! Are you having this issue with one specific project or all projects? (Including creating a new project from scratch) If it is a specific project, it could be some specific files, plugins, etc that are from either a different UE version or a different OS.

It happens, when starting Unreal Editor 5.0.3.

I see. You’re not having this issue with any other version of Unreal Engine?

No problems. it works with older versions (4.22 or 4.25) here on ventura, montery, big sur. Unreal 5 not tested.

Ah, Unreal Editor 5.2.1 is working now.
