In the meantime, I updated to 18.1 beta to see if it solves the problem, but no improvement on this issue.

I didn't write feedback, since there is no 18beta4 in the list, and I waited 1-2 days with it to see if it would be fixed, but there was no change. In the meantime, I installed the 18.1 beta to see if it would solve the problem, but unfortunately there was no improvement.
