VIZ-3981
Encryption issues with settings may render the UI unusable

If the secret key used for encrypting sensitive settings (such as data connection passwords, email credentials, and AI profile API keys) becomes mismatched with the encrypted values in the metadata database, a cryptography.fernet.InvalidToken error occurs and the UI becomes inaccessible, and you cannot correct the issue through the interface. This can happen when the .keys file in the .arc directory is deleted, replaced, or not restored alongside the metadata database during a backup, restore, or migration operation. This affects Cloudera AI and Cloudera Base on premises deployments.

Workaround:

Restore the original .keys file from the .arc directory to match the metadata database.
