Is there any way to revert to the last beta (version 16)?!

No. My recollection is that it expired on 5/15.

Best,
Jim

Try to open file menu while mantain Alt key pressed and select “Close project and clear interface settings”

Alt+File → “Close project and clear interface settings”

Hope it helps

:wink:
Glad it helps you.
I deal with similar behavior in beta 12 specially in dark mode, I think it´s a bug, but I couldn´t be able to reproduce it.
