Clion keep failing to save/update code and compile proper version!!!

Hey

This is going down the drain from 3 releases now. 1st with super slow refactoring. Now I get random "Could not save file, revert" message boxes. Spamming Ctrl+S does not do anything. Lately when I hit ctrl+D to duplicate line of code, or ctrl c/v to paste stuff also cause massive lags ;[

This is ridiculous. I restart clion and half the code is gone!!!! I'm reverting back to 2020.1.3

Regards
