Spinning Beachball + "Application not responding" when working on edit...
Hi All!
Working on a project with Premiere Pro 23.4.0.
Using an iMac (specs below):

Project was working smoothly until a week or so ago. Last few days it has stopped a few minutes into the edit and has frozen with the beachball 😞 ...
Tried starting a new project on the desktop and importing the old project, deleting cache, lowering playback resolution. All helped temporarily, but the project soon began stuttering and freezing again with the beachball.
Any tips, tricks, solves would be GREATLY appreciated!
