Playback Freezes in Premiere Pro (Beta) 24.1, runs fine in standard Premire Pro
Been editing this project in Premiere Pro (Beta) 24.0 on/off for 3 weeks.
Went to make some final amendments today and realised that there was a new update available, so naturally, updated.
Opened project following update and now there is no playback, I can't scrub through my timeline, and the video won't export (see below screenshots).
I've done a fair amount of research, and tried common suggestions - resetting workspace layout to default, render and replace timeline, copy to new project, copy to new sequence, changing from GPU to program optimised render, etc., and no results.
Project runs fine in standard Premiere Pro, but 24.1 is causing problems.
Tried to roll back firmware to 24.0, but the program only opens in the background, and is only viewable in taskmanager.
Any suggestions please?
