Program freezes after a few minutes or sometimes after a few seconds of usage.

I installed the new 2021 version of Premiere and that's when the problem started. I would start working and the program would crash only after a few minutes of usage. The problem with any files longer than 10 mins. 

I had reinstalled the program twice, reset my pc, lowered ram usage, and cleared out scratch disks but the problem still persists, After the program just freezing the video player is all white and doesn't work. I can't change workspaces either, any help would be greatly appreciated. 

Here are some screenshots.
