premiere pro beta 25.0.0.044 crashes every time I move a video event on the timeline.

It's impossible to use premiere pro beta today. After the last update it closes by itself every time I move a video on the timeline. If I put too many videos on the timeline it also closes.

When I try to go back to the only old version of PPbeta available (24.6), two "phenomena" happen:

1. I can't open the latest version projects due to incompatibility.
2. When I create a new project, it goes back to the home screen.
