A new crush episode with N10.3

My N10.3 is crushing when Im trying to open it. I cant believe Im still working on 10.2 and acutly never enjoyed the 10.3, and of course i will not go for the N11 after this.

Im with osx Mojave 10.14.6, tried with and without 3rd side plugs, pref and all the other tricks inculding reinstall the 10.3 again.

Can someone help?
