@mamirof Can you tell me more about the key that is being used?
Was it imported or created via the app? If imported it’s possible the specs of the key are not accepted. Do you have any details on this?
If not imported, any idea which passbolt version was in use when it was created?
The team is saying that downgrading to a previous version of the extension can get you started, and then create a new user, transfer over your passwords(Resources) to the new user and grant ownership, then delete the old user.
In Firefox you could install the extension via a file, and it appears in Chrome by turning Developer Mode on in chrome://extensions/ and load an unpacked file.
