Steinberg Activation Manager MAC OS issue

I installed Cubase 12 but I cannot activate my license because of this error in Activation Manager:

“Steinberg License Engine is Not responding… An Unknown Error occured etc”

It’s a very common issue with MAC osx, mine is 12.6.3.

I need Cubase to run on this computer, what do I do?
YES, I’ve restarted the damn computer many times, it does not help.

Thank you,
