Welcome to the community, and sorry for the issue. Which version of Premiere Pro are you currently using? Have you tried resetting your preferences? If that does not work, please share a screen recording of the issue.
I have downloaded the 22.6.2 (Build 2) version. Now some projects and all the Mogrts will not load. The error (attached) indicates it is 'not compatable' with my version although I have used them BEFORE upgrading to the 22.6.2(Build 2) version.
