Server sync error

I can't sync anymore to the server. Reinstalled allready my complete creative cloud twice, but its still not working. When I go to the browser version, I can add directories and than it will sync but when I do this from my desktop, it gives an error. When I go to my creative cloud online account it says I have more than 300gb of data. Thats not true because otherwise my macbook would explode. I started empty the trashed files which went back to 6 years ago. After some errors there, my account says this directory is empty. Which is not true. I think my account is corrupted.
