Premier Keeps Freezing

I have had many issues with premiere recently. Every time I open it and start editing, it freezes and I have to force quit. My computer is updated, premier is updated, and I have proxies made in 1080p so this shouldn't be an issue. I watched mulitple videos on suggestions but nothing seems to be fixing the problem. I also tried on a friends computer and it was freezing on hers as well so I know its an issue with premiere. I have never had this issue before and I am stuck on what to do.
