Unity fails to launch on MacOS

Unity Engine
1

I’m on MacOS 11.3, Hub 2.4.5, and alpha 2022.1.0a7.

I installed the alpha through the Hub.

When creating a new project, or attempting to launch an existing project with the alpha version mentioned, I see a very momentary “blip” of a program opening and closing immediately in the Mac dock. I am assuming this is the Unity editor starting and immediately stopping.

After this nothing happens. I would expect the Unity editor to appear on my screen.

Hi!
Please check the Editor log, there should be some info about why this happens.

Can you trying reinstalling?
It looks like some file that is required is not found.

Reinstalling the hub and the alpha editor fixed whatever issue was there.
