Fresco Freezing/Not Advancing Past 53% Walk-Thru Tutorial + No Way to Exit Fresco

I thought I'd try Fresco to complement my Ps work (primarily photo-oriented - seemed like it might be cool to try some digital painting on photos...).

I launched the Fresco interface (on Win 11 Pro, AMD RX6800 XT up-to-date) and after several tries was unable to get past the 3rd-4th step in the self-guided interface tour. It consistently freezes at the 53% completed point and won't let me do anything else in Fresco either. I cannot go forward or back in the tour. The entire interface locks up.

I tried ESC, I tried hitting the "X" at upper right of my Win 11 interface. I can't even exit Fresco. I tried re-launching a few times. Same exact experience every time...

It's very frustrating.

Fresco needs some troubleshooting... any tips re: how to work with (or, around) these issues if we want to get oriented to the UI? Thx.
