Your blockchain is corrupted. Most likely you did a hard, not graceful shutdown like pulling the power plug while the blockchain was writing files to your disk. Try to avoid that in the future.

```
bitcoin | 2021-08-01T19:05:31Z Fatal LevelDB error: Corruption: not an sstable (bad magic number)
bitcoin | 2021-08-01T19:05:31Z : Error opening block database.
bitcoin | Please restart with -reindex or -reindex-chainstate to recover.

```
