Icon for tracker not working, getting syntax error

[Markoh75]

Hi!

Last weeks I had problems with the tracker icon. It says that I have new items in the tracker.
I double click on the icon and then i get error: "Error while opening document, document cannot be found."
If I press OK on that and next error shows: "there was an error opening this document. The filename, directory name, or volume label syntax is incorrect"

Here is the twist, if I now click OK and directly on the tracker icon again it works.

So this syntax error seems to be shown only when I am starting the tracker when acrobat is closed.

I have Acrobat Pro DC Version 2018.009.20050 and i have uninstalled it and reinstalled without solving the issue.
Acrobat is running on a Windows 10 Enterprise
Version 1709
OS-version 16299.98

I do not remember if this problem started after the install of the windows creators update...?

Any ideas?
