Form still works, can't access results

Greetings.  Have a user who created a form, and was able to access the results, but a few days later lost access.

The form still works and lets people submit entries, but when he tries to go to the results page he gets the following.  "Sorry, something went wrong. IT Policy has disabled the collaboration feature."

The form also no longer shows up in his list of forms, or in the recycle bin.

Old forms still work, new forms still work.  No other issues with any other forms in the company.  Any suggestions?
