Fatal Cloud Error: DoUnserialize

Hi, I am unable to open my cloud project. The console shows the error: Error: the element passed to ObjectJsImplementation::DoUnserializeFrom is not an object.

I have already tried:

  1. Clearing browser storage/IndexedDB (it is empty).
  2. Logging in/out and using different devices.
  3. Deleting other projects to stay under the limit.

The ‘3 dots’ menu only shows the Delete option, so I cannot download the file to fix it manually. Could a moderator/admin please help me restore the project to a previous save from 48 hours ago
