imovie was working great. i was running mont. 12.1. i tried to start it the other day and it just hangs. beach balls and never starts. i let it run overnight. the next morning it had still not opened. i don't think it ever will. i updated to monterey 12.5 and still the same thing. i'm not able to change any settings. as soon as i start imovie it hangs and i can't change library or do anyhing.
i'm running a MBP 16" M1 max 32gb ram, 2TB SSD.
Check to make sure that you have sufficient application space on your drive for iMovie to open. Sometimes our drives can fill up without us realizing it. You would want about 10GB on the drive.
Also try updating iMovie to current version, since you have updated your OS to Monterey 12.5.
To see if there may be some corruption in your present iMovie library, try deleting preferences as that will cause iMovie to open in a new blank library. Open iMovie while holding down the Option and Command keys and select to delete preferences in the box that appears. iMovie will open in a new blank library. Reopen your old library to get back to your projects. Possibly you may need to reboot to set the changes. Deleting preferences is a safe procedure that will not cause data loss or disruption to your project.
If iMovie still won't open, try going through the following diagnostics to see if you can cure the problem.
Shut down and reboot
Try shutting down and rebooting, as sometimes that will will cure some issues.
Safe Mode
You could also try booting up in Safe Mode and, after everything loads, immediately shut down and reboot in normal mode. Then see if iMovie will load.
