2021 MACBOOK pro 14 adobe premiere pro freezes on opening project

Starting a new project and importing older version project files is not a workaround, it's the recommended way to open older version project files. Or do you have to open projects started in this particular version of Premiere by using this method?

Hello Grant,

I wonder if clearing your preferences and trashing your media cache would help. There may be something left over in those files that isn't supposed to be there.

Media Cache: FAQ: How to clean (delete or trash) media cache files?

Let me know if this works!
