Corrupt or Otherwise Broken Audacity Project Recovery

Hey folks - need some help here - we’re at step 9 and we’re getting the error message: “files is not a database” - we think this might be because the file we had was the “.aup3-wal” file instead of just “.aup3”

When we tried editing the command line to include “.aup3-wal” it said “unable to open database file” and then we changed file to an “.aup3” and it gave the “not a database” error

We don’t have an original “.aup3” as far as we can tell - are we screwed? Big thanks for any support
