I had the same issue last week after doing a save copy in session for backups. After I make the back up at the end of the session, I open the new session to make sure it works. But every session that I backed up, would not open. After restarting they would work, but the next day they would still lock up when the video was loading. I moved back to 2020.9.1 and everything went back to normal. Would like to know a good resolution to this.
