Hi all.
Since about mid of July, we are experiencing the following strange and not-so-much-telling error message box:

It happens to many, if not even all of our users, immediately after login, and sometimes even again during work.
It might be related to the 10.14.6 update, but could also be a co-incidence.
From what I can tell now, it seems not to bring any lack of functionality experienced by the users, but it just more than annoying.
Has anyone ever seen this window? If yes, where does it come from, and how to remediate this? If not: Any ideas how I could find out about causing process?
Thanks and best regards
Chris
