Data Recover from Encrypted LUKS Partition | Missing Files

I have been having some issue unmounting my encrypted drive recently. This lead to it being forceably removed instead of ejected. It appears to have some done some damage to the drive as, although I can access some of the data within it, certain portions appear to be missing. Are there any tools I can utilize to attempt to recover any lost data? Thank you so much for any help. Some of the files on this drive are very important to me and I want to ensure I do everything possible in attempting to recover them. And in the future, utilize a more robust method of backing up data.
