I got an error message for a fatal error with the database and Bitcoin Core quit, when it starts it attempts to resync but it always freezes around block 255672.

I've tried to start it with bitcoin-qt -reindex but I get the same result after several attempts

I deleted all the blocks and restarted and it downloaded for several hours and then I got this:

I backed up my wallet.dat file through the GUI so I think my coin is safe.

How can this be repaired?

Thanks!
