Minecraft v1.16.4
Forge v35.1.13
Shrink v1.0.5
Rediscovered v1.3.4

While in creative, I had spawned a Piglin and then I assume the game crashed when the Piglin changed into a Zombified Piglin. The crash report mentions both Shrink and Rediscovered's Pigman. It crashed both the client and the server.
