Beta Premiere Pro Crashing / Unable to open Beta created videos in Premiere Pro latest version

Hi, I currently use Premiere Pro Beta version as I was told a few months ago to use this app instead of the usual Premiere Pro due to bug issues. I have been creating my videos in Beta.

Now I am experiencing an issue when I select "effects" in Beta and the app is crashing / closing on me. I have uninstalled both Beta and the usual Prem Pro and reinstalled. All versions are currently up to date.

Now I am unable to open my Beta created videos in the usual Prem Pro - the error message says that the video was created in a newer version app and therefore cannot be opened in Prem Pro.
