We recently updated Umbraco Forms from 10.1 to 11.2.
Now when I try coping a form in the Back Office, I get a 500 error from "umbraco/backoffice/UmbracoForms/Form/CopyForm" method.
Update: this happens whenever I try saving a form. Or when I try creating a new form.
Response is {"ExceptionMessage":"Object reference not set to an instance of an object."}
Nothing of value shows up in the Log Viewer.
The existing forms seem to be working on the front end, but I cannot create or edit any forms.
Help please!
