Files not found. How can I recover them?

Every time I start revit, I get 3 error messages from external tools.
-"Failed to initialize the add-in "CollaborateDB" because the assembly "C:\Program Files\Autodesk\Cloud Models for Revit 2025\CollaborateDB.dll" does not exist."
-"Failed to initialize the add-in "Collaborate" because the assembly "C:\Program Files\Autodesk\Cloud Models for Revit 2025\Collaborate.dll" does not exist."

Restore a backup copy of the central model:

1. Start Revit.
2. Click Collaborate tab Synchronize panel (Restore Backup).
3. In the Browse for Folder dialog, navigate to the copy of the backup folder for the central model (created in step and click Open.

I cannot find that backup folder.
