How did it happen?

Minecraft Version: 1.20.1
Forge: 47.3.7
I use the newest IE mod(1.20.1-10.1.0-171 from curseforge)
I first noticed this on a server, but it happens in singleplayer as well.

It is happend when display .litematic schematics file to the world (not use replace or other mode to place blocks from schematics)
When display .nbt schematics file to the world, it is not crash and everything works well.

.litematic schematics file:
QunYuGe.zip
(this schematics file may be contain other mod blocks, but in other modpack that have those mods, the bug will still apper. Crash log on modpack Minecraft: modpack-crash_crashBothSinglePlayerAndMultiplayerServer
