The bug
I just started server. Might have dependency on MC-133816.
Appears that it happens only on this world. Is this world corrupted? Did not used any third party tools.
1.13.1: latest.log

Created in pre 10.
Confirmed for 1.13.1-pre1 and the server crashes because of MC-131071.

Please check if that's still an issue for you in the latest 1.14.4 stable release or the latest 1.15 development snapshot.

1.14 did not crash. Some errors apper, becouse of world got corrupted in very old version (1.13 pre 10).

Is this a new 1.13-pre10 world or was the world loaded in snapshots/other prereleases / 1.12.2 ?
