If the files on the original drive are important to you I recommend you find a local recovery specialist and take it to them. Tell them the files you want to save are in an encrypted vault and you need to be able to signon to the vault. Once you can signon immediately export the files to a backup device.
Good luck.
PS I heard that flakey drives sometimes work if they have been stored in the freezer overnight. I have never had a need to try this so I can’t vouch for it.
