MacOS Big Sur
Spent 80 mins with Adobe on this just yesterday (January 18). The long and short of it? Yet another bug for this latest Premiere Pro release 23.1 .
No amount of re-booting, removal of third party plugins, cache clean, preferences removal, workarounds, nothing seemed to get Premiere Pro to be able to run a typical Project Media Manage operation.
Honestly, at this point, I really REALLY wish that Id not updated to this version. Myriad problems, including the now well-documented timeline lag issues.
I have spread the word to all editors that I know to avoid updating to 23.1 at all costs.
