corestorage damaged

I got a core storage damaged error when trying to repair my drive. The system was only booting to recovery, but I was able to unlock the disk and attempt to reinstall the OS "was saying High Sierra, then changed to Mojave after reinstall". But now when I boot I get the user file vault login and then it just fails to load. First Aid returns no errors, I can't boot into safe mode, only thing usable is recovery and single user sign on. I believe I can repair if I fully wipe the disk and start over, but I would like to recover the data prior to doing that. I have admin password and the file vault key.

So you have the filevault psswd but can not proceed?


But you can boot into Safe Boot and login successfully ?
