Beta8 Activation/Lauch issue UPDATED, AGAIN

The beta8 version in my case has some activation problems, both with the dongle and with the serial number. Essentially it gets stuck on the first loading screen. No problem with beta 7. Waiting for beta9

UPD: The problem is not related to activation. If I delete the preferences Resolve 17b8 starts but the ultrastudio output does not work. On second start it crashes again. Maybe the problem is related to Big Sur? Maybe to the latest desktop video? I see there are a lot of changes in this version. I don't know, but as I said no problems with beta7.

UPD2: I can confirm that version 17b8 starts correctly on MacOS Catalina, on my 'old' laptop.

UPD3: Today, even on my laptop, same activation problem. Ok, I give up. B8, for some people, is definitely broken.
