Here is the error I get:

New file name: invalid type: null, expected a string

Old file name: /Users/toxxxxxll/Library/Mobile Documents/com~apple~CloudDocs/Documents/Screenshots/CleanShot 2021-03-26 at 16.56.34@2x.png

Also, the contact page on the main website gives a blank page, so I don't have any other way of submitting support requests.
