Restore Data when bolt and sqlite are corrupt

I have a pretty big problem. Due to an unfortunate circumstance, the influxd.bolt and influxd.sqlite files are corrupt and cannot be restored. However, I still have all the files in the data and wal directories. Is it possible to restore the data somehow?

Unfortunately, I have already tried the following solution without success: Recover installation after OS reinstall

Any ideas?

Thanks a lot in advance

Unless you have a backup, unfortunately just with data and wal directories I don’t think it’s possible to recover.
