2022.1 R10 instead of 2022.1.1 R4...So this was really a very long time issue. i can remember it.
and as i told you in past too, working on heavy big projects makes it difficult to update all the time to the newest small new versionsteps. some projects go over 1-2 years parallel to others. its really hard because often issues evolve with newer versions. so now i will work with newest version and hope, that everything works.
in this case, the step from x.x.1 Rx made a difference.
thank you for your help.
