No splash screen on Mac version and very long launch time

[Mattk70]

Describe the bug The splash screen fails to appear when launching the Mac version. Also the application takes 85 seconds to open on my M2 Macbook pro.

Expected behavior Splash screen should appear, and launch should be no more than a few seconds.
