I'm running Opera Developer on a MAC Big Sur version 11.2. After a recent Opera update, print dialog stopped functioning. If I click control-P or on a print icon, the Opera print dialog window appears and hangs. All the entries are greyed out, so there's nothing I can do except close the window. I can print using Command-Shift-P. Then the MAC print dialog window appears. Sometimes, however, the content printed isn't configured the way it would be if printed using Opera's print dialog window. Other browsers aren't affected, so it's an Opera issue.

I'm reporting the same problem. I've had to repair lastpass twice already today. And that's without any closing of Opera. Something other than launching and closing Opera seems, therefore, to be causing the corruption.
