Save it as a file.

The recovery key should be printed.

Check your Microsoft account or any folders that may contain the key if you have saved the file. If you have printed the copy, locate the paper and trust that you have not discarded it as scrap paper.

Another option is to verify whether the password was retained on the drive during the sign-in process, provided that you have a password manager.

If the recovery key is unavailable and the password is forgotten, there is no alternative method for retrieving the data.
