Steps to Reproduce

1. Set up a Fabric 1.21.1 dedicated server
2. Install The Aether (1.5.11)
3. Start the server
4. Join the server as a player
5. Wait between a few seconds and a few minutes
6. The server crashes

Apparently the crash happens after an entity dies.

What You Expect To Happen

I expected the server not to crash

What Actually Happened

The server crashes

Additional Details

The crash only happens on the server, not in single player worlds.
In the server world I had previously installed trinkets. I then tried to install Accessories and Accessories Compatibility Layer, but the issue is the same.
