Unable to export in Lightroom

Lightroom 7.2

Unable to export edited photos:

"Unexpected error performing command: bad argument #1 to 'stringByAppendingPathComponent' (string expected, got nil)"

Exporting pictures were fine an hour before, all of a sudden nothing works. "SHIFT + E" does nothing, the error message above appears only when exporting as JPG (small), JPG (large) & Original + Settings.

I've tried resetting my preferences, reinstalling lightroom, removed similar named files. Please help!

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

I will reach out to you privately to get some debugging info.
