Epic Games Installer Problem Endless Update Loop (MAC M1 Max)

Dear community!

I received the first device for the new CAD standard (Apple MAC Studio M1 Max) in the office and set it up.
For the rendering tasks (besides ArchiCAD) I have to install Unreal Engine 5 for Twinmotion, which in turn can only be obtained via the Epic Games Launcher.
This is on install wizard but in an endless update download/check/install loop.

Already tried:
-Install as administrator user as well as employee user with input of admin user
-older version installed (but will be forced to the identical update process in the wizard)
-SIP (System Integrity Protection) disabled in recovery mode via terminal (csrutil disable)

  • Latest MACOS Ventura version
    -Ticket opened at Epic Games (may take time)
    -Requested Educational Offline Installer of Unreal Engine 5 (will be rejected wsl because no educational institution)
    -Research Google and Youtube

Very annoying that such a simple forced launcher doesn’t work (Ventura released 8 months ago and Apple M1 processor almost 2 years ago)

Video how it behaves here:

Do you have an idea?

Thanks in advance!
