[Render thread/FATAL]: Preparing crash report with UUID f9d0d804-2d1d-4875-ac71-02dd3040

The following content is machine translated:
I have some mods installed in my Minecraft.
When I first entered the Nether in multiplayer, the game client crashed and told me it was an entity that wasn't working properly. The entity type is: minecraft:piglin.

But the server didn't report any errors.
So I created a new single-player save to test, and sure enough, the same problem occurred, and the entity was still not working properly.
I can't figure out which mod has the problem, or is there another reason,please help me find the problem.Thanks.
My Minecraft game version is 1.16.5, and the forge version is 36.2.34.
