After I broke an ender crystal, the server fell into an unresponsive state and eventually crashed, and after checking the crash report, I found that it was caused by this mod.
Minecraft version:1.20.1
Mod version:5.0
Crash reporting:
crash-2023-09-10_10.52.38-server.txt

I also found that your "Spoorn Armor Attributes" mod has a similar problem, which is trying to append damage to entities that no longer exist.
Another crash report:
