I got error after rebooting my Mac

[Security breach]

Hi
i've been using bitcoin core wallet 21.0.1 on my mac untill yday. but after i rebooted the pc yday(for other reason) btc core started showing an error. when i open it it stucks on loading block index, and shows this error message.
'You need to rebuild the database using -reindex to go back to unpruned mode.  This will redownload the entire blockchain.
Please restart with -reindex or -reindex-chainstate to recover.' when i clicked ok, debug log like this appeared
should not be overwriting a chainstate
Error: Error opening block database
Shutdown: In progress...
scheduler thread exit
Shutdown: done
Anyone knows the solution?

Can you post the whole debug.log here and don't forget to put it inside the "insert code tag" with icon #.

I think the reason why you get this error it's because you have corrupted blockchains.
I'd like to suggest is to try manually reindexing the wallet through the terminal.

Use this command below

Code:

/Applications/Bitcoin-Qt.app/Contents/MacOS/Bitcoin-Qt -reindex

Let see if it will work.

I think if your wallet is set to pruned mode and you use -reindex it will only download the latest blockchain and delete old blockchain you recently downloaded.

I don't know what would be the outcome after you use the command above but better add prune=(N) at bitcoin.conf file so that it won't download the whole blockchain.
