Photoshop error, Photoshop stops working, 2021, can't save

I have this nasty problem that if I make an action like cut and paste one object the paste is empty and after that I can't save the file and nothing works! Even the copy and paste starts to not work, only makes this error sound. I Uninstalled Photoshop, restarted computer, problem is still there. And ofc it's 2h before I have deadline to opera BG! This is terrible!

Using MacBook Pro, Big Sur
