sync error 1553991583

Syncing my zotero library under windows 10 at my workplace ends up with an error message. This is new. I do have a lot of trouble for long time with syncing on my Linux Notebook. I do not know if this issue under windows has to do with the issue on Linux. See Report nr 2086022575. Maybe it also has to do with an upgrade on Win 10 our IT-department recently made from 16.04 professional to 19.03 enterprise.
I would like to understand what the problem is to solve it.
Thanks for any hint.
