Thanks for reporting this!

Can you reproduce this on 1.13.x experimental builds?

This seems to be linked to wider issues regarding config saving on 1.13+, possibly linked to the SnakeYAML upgrade.

Seems to work. I've reused my old config, where the problem was.
After I deleted it 3 times or so before, it was magically fixed as well.

When using the old config, and setting new spawn etc, it doesn't seem like the error occurs more.

This issue has now started happening to me, doing /spawn or /setspawn completely crashes the server

@FuneralSuits with the experimental build, or the regular?
The experimental fixed it for me.

@Arkobat Just loaded it up using the most recent experimental build and it works great!
Thanks!
