SWX 2019 freezes every 2 minutes

We are using SolidWorks 2019 SP02 and SP04 (WIndows 10 Built 1809 and also 1903) and have the following problem:

Exactly every 2 minutes SWX freeze for 6 s (if we are in company domain for 15 s).

If network is disconnected it don't freeze!

Same problem on 4 different Computer!

This happens with every assembly, part and also no part - only by rotating the ucs.

 

Has everybody an idea or is there still a solution available?

PS: I replied to a similar question in another thread, but this question was based on an import problem. And with Imort the described problem has nothing to do!
