I've found only one other instance of that specific error message occuring on export:

There was no solution posted for that.

Similar but not identical error messages occur when you try to delete photos, and disabling the LogiOptions plugin installed by Logitech cures that. So you could try disabling LogiOptions (which Logitech silently installs with its utilities) if it's installed in your LR -- do File > Plug-in Manager, scroll to LogiOptions and select it, and in the Status panel on the right, click Disable.  Restart LR.

Let us know if that helps (I'm doubtful it will...).

This did not help

I suggest you post a bug report in the official Adobe feedback forum, where Adobe wants all bug reports and feature suggestions: 
https://www.lightroomqueen.com/send-bug-report-feature-request-adobe/

Be sure to include the first ten lines of the menu command Help > System Info.  Provide all the details, rather than linking back to this thread -- experience shows that Adobe developers tend not to follow the links.
