Additional context

Have the server been shut down forcefully before? Such as system crashes like BSOD, task manager kill or powercut?

There is a broken chunk near your friend's location. The crash is to protect the chunk from being regenerated.
There are many causes of this issue such as unclean shutdown, disk issues, or general system instability.
But the only proper way to resolve this issue is to restore from backup, or try to repair it manually after backup using tools like mcaselector.

No, my server hasn't been forced to shut down.
All server shutdowns to date have been done in accordance with normal procedures.

Ah, thank you. After restore from backup, this issue is resolved.
