You got some corrupted data.
Did you kill the process? Or is your hard drive very old? External hard drive?


Try reindexing by using the -reindex parameter when starting bitcoin core.
If the errors keeps coming, you might want to check/replace your hard drive.

Either reindex or if you prefer, you can try to reindex the chainstate instead. It will help you to avoid downloading the entire blocks over again (also avoiding the time consuming indexing of your blocks) and instead rebuilds your chainstate only.

You can use -reindex-chainstate when starting Bitcoin Core.
