Reproduction Steps

It's been a long time since I started playing the game.
But this problem happened suddenly

Additional information

A crash occurred while playing the game.
To troubleshoot the cause, I looked into the logs and identified an issue called "Ticking Entity". It was also confirmed that the target was an ‘iron golem’.
I thought there was a low probability that there would be a problem with the iron golem, so I looked at the log closely.
Among the log contents
at net.minecraft.world.entity.monster.Illusioner.handler$cal000$friendsandfoes_damage(Illusioner.java:1245) ~[client-1.20.1-20230612.114412-srg.jar%23466!/:?] {re:mixin,pl:accesstransformer:B,re:classloading,pl:accesstransformer:B,pl:mixin:APP:illagerinvasion.common.mixins.json:IllusionerMixin,pl:mixin:APP:friendsandfoes-common.mixins.json:IllusionerEntityMixin,pl:mixin:A}
I am writing this article because that was the case.
Even if the mode is not the problem, I would like to know the simple cause.

Thank you for this report, it's actually problem in the mod, will try to release fix as soon as possible (hopefully today).

Should be resolved with 2.0.2 version.
