Hello, last node red update has deleted all flows for me. Restoring a home assistant backup fails. Here is the message:  
The credentials could not be deciphered.

The file containing the flow credentials is encrypted, but the project's key is missing or invalid.

The file with the flow credentials will be reset the next time you deploy it. All existing flow credentials will be deleted.

Is it still possible to save this?

Restoring a full HA backup also doesn't work anymore.
