error parsing properties list from file in premiere pro cc 2020

Create a new project file. Go to the MediaBrowser, navigate to the old project file and select it, then right-click and import the assets from that project one by one. See if this works in the new project.

Ok, the nuclear option is next ... Adobe CC Cleaner Tool ...

Download this, and yea, it's got a weird old-style DOS-looking interface that's keyboard only. The instructions say to uninstall the app first then run the Cleaner Tool ... don't. (Yea, I've plenty of experience with it.)

Run the Cleaner tool with the app still installed will work and does so every time. Uninstall first, and it may or may not.

What this does is go through every place on your computer that Premiere stuffs things on installation and clean them out. Including the ones that a "simple" uninstall doesn't get.

Then reboot the computer and do a fresh install.
