I tested this with Minecraft 1.16.6 using Forge v36.1.0.
Agricraft Version 3.0.1
InfinityLib 2.0.3
Create 0.3.1c

Used just those mods in CurseForge on a brand new modpack and created a new world. Everything loads fine until you hit Escape to get to the options menu and the client crashes.

It then comes up with the following error:

The game crashed whilst unexpected error
Error: java.lang.NullPointerException: Unexpected error
Exit Code: -1

Here is the Crash Report as well:
