Premiere opens but I get "no available windows"

[Magnuzzz]

Hi,

I just got a MBP M1 and first tried to migrate from the old machine without success. According to Apple support my old machine was too messed up internally for the migration to work. So yesterday I did a clean install of Monterey on the new MBP and downloaded all of the latest Adobe stuff. I opened my Premiere project (on an external Dell monitor) and everything seemed fine. Today when I open the same project at my studio using a different monitor nothing at all happens. Premiere is active in the dock but when I click the dock icon I get a message saying "no available windows". The entire menu is also greyed out.

What could be going on here? I looked through a bunch of forums/Youtube but didn't come across this problem. In my System prefs -> Display I see two screens even when I don't have anything connected. One is my MBP screen and the other also claims to be my MBP but 1080 60p. Perhaps this is my old MBP haunting the new machine? Could all of the windows be on there?

Thanks in advance,

Magnus (on a deadline...)

Do you have Mission Control set up? Have you told macOS that you want Pr to only open on a particular monitor or desktop?

You may want to try opening up Pr on your MBP screen at home, and then saving and closing it. Then when you're at the studio open Pr up again and move it to the external monitor there.

If System Preferences is showing 2 displays when you don't have a 2nd display connected, you're having a macOS issue, not a Premiere issue. I've seen issues with old mini Displayport cables not being compatible with certain monitors.

Can you take a screenshot of this "no available windows" message?
