Ran into an issue with Premiere Pro 15.2 on my M1 Mac mini running Big Sur 11.4. I had a project open and walked away from the computer. When I came back, I tried to drag in footage (.mp4). The program immediately crashed. When I tried to start it back up again, it froze on the splash screen. I didn't get any of the quick flashing text to show it was loading plug-ins, etc. It just hung on the static splash screen.
opening it from the menu without the project thinking that was the issue
opening the current Beta 22.0 on its own which I also had installed
Both had the same issue. As soon as they hit the splash screen, Activity Monitor shows that they are not responding. Then I tried:
uninstall/reinstall of 15.2
Opened After Effects, Media Encoder, and Illustrator which all worked fine
ran repair for Adobe CC Desktop app
ran the Creative Cloud Cleaner tool for Premiere
created a new user and tried to open it from there
tried signing out of CC and signing back in
Uninstalled Premiere, Premiere Beta, and all versions of Media Encoder then reinstalled without Beta versions
Every time it's the same. I've submitted several crash reports and I haven't found a solution anywhere. At this point I've basically tried everything I could come up with short of a clean install (which I did last week due to synch issues) and Premiere still will not open. I desperately need to get into the program for work so if anyone has any fixes, I'd love to hear them.
