Crash seems to only happens when a player is logged in. Server has been idle for 12+ hours with no crashes. Within 5-60 minutes of a player joining is when the crash occurs. Server has not crashed if either gamemode is set to Peaceful or mob spawns are disabled.

Server is running on an Ubuntu VM and is managed through Crafty Controller. I had moved the server to a Windows 10 VM and ran the server directly without Crafty and the crash persisted.

If I can provide anymore information please let me know! Thanks!

Start with the linked stack trace at paste.gg and the reported Paper git-Paper-405 (Minecraft 1.20.4) environment. Compare server behavior with plugins disabled, with a player logged in, and with Peaceful mode or mob spawning disabled; the issue is done when the recurring crash is reproduced, narrowed to a cause, and prevented or clearly documented.
