2022-02-20T19:10:24Z [default wallet] Rescanning last 724202 blocks (from block 0)...
2022-02-20T19:10:24Z [default wallet] Rescan started from block 000000000000000003***************************************************f60...
So it is rescanning the entire blockchain. The 00000003***** is just the hash of a block you can copy & paste it into any block explorer and it should tell you what block it is.
724202 is just about the last block so that is fine.
Make a backup copy of the wallet.dat before you do anything else.
Then make another backup.
If it's not dumping an error into the debug file something is probably very corrupt with it.
Try to salvage the wallet. A small discussion on it:
