Versions

• Minecraft version 1.16.4
• Forge version 35.1.29
• Mod version easy villagers: 1.16.4-1.1.17
• Mod version create 1.16.3_v0.3c

Other mods
Yes there where other mods, it's Enigmatica 6 with Easy Villagers and Easy Piglins added, but I don't see any other mods in the stacktrace.

This is an issue of create. Forge 35.1.16 added the parameter hitVec to the RightClickBlock event.
They create the event without initializing this parameter, causing a NullPointerException on my side:

This is the Forge commit introducing this change:

I'm gonna create a fix for my mod, but you should definitely also report this to the create devs, as it could cause crashes with more mods.

The same applies for computercraft
