14.9 freezes every time I try to open a project

[Bobby Boson]

Premiere opens to the wecome screen, but when I open a project it freezes before opening. If I open premiere, empty the media cash, then click open, it will work. Any permanent fixes?

I've never encountered this with any previous versions of premiere.
