Someone brought this up in the discord and after some testing was able to reproduce with just apotheosis and dependencies with Embeddium.

When a trident has both piercing and loyalty enchantments and used on a mob, it can cause the game to freeze and exit without a crash report and the log was not helpful. They found it mainly occurred when attacking an enderman with the trident.

Creating an issue here as apotheosis had a mixin to allow piercing on the trident.
Curseforge profile export:
Trident crash with Embeddium.zip

Its not Embeddium, the issue persists without it.
