Unfortunately, the recovery code provided by Bitwarden serves only the purpose of disabling the 2FA on your account. There is no method for by-passing your master password. Without your master password, your only option is to start over with a new account. If you are logged out of all Bitwarden apps on all devices, then there is also no mechanism for retrieving your vault data. I hope that you have been making backup copies of your vault, or else you have truly lost everything.
