Hi,
An update on this.
Disabling the zip background scanning by Windows Defender did remove most of the high CPU for me.
However while using Outlook and trying to save an attachment in the shared folder I noticed high CPU again...
As the zip integration in Windows now was my direct suspect I decided to completely remove the integrated zip handling by windows explorer.
For me acceptable as I strongly dislike windows explorer's behavior to treat zip files as a folder. Already used 7zip for opening/creating zip files, so nothing is lost by doing this for me.
So I used the steps as laid out here:

Restarted my VM to apply that change.
...and that indeed now also seems to fix the high CPU in the "save as" dialog.
Of course not having to take any of these workaround steps would be nicer, but I personally am at least happy to have a responsive VM.
Will let you all know if the problem does come back again (hopefully not)
