[Error :Il2CppInterop] Nested type ToolbarButtonSize on GUI not found!

[michaelwuwar]

When I start BepInEx, I get a fixed error:
Unhandled exception. System.NullReferenceException: Object reference not set to an instance of an object. at Il2CppInterop.Runtime.Injection.Hooks.GenericMethod_GetMethod_Hook.Hook(Il2CppGenericMethod* gmethod, Boolean copyMethodPtr) in /home/runner/work/Il2CppInterop/Il2CppInterop/Il2CppInterop.Runtime/Injection/Hooks/GenericMethod_GetMethod_Hook.cs:line 22 Unhandled exception. System.NullReferenceException: Object reference not set to an instance of an object. at Il2CppInterop.Runtime.Injection.Hooks.GenericMethod_GetMethod_Hook.Hook(Il2CppGenericMethod* gmethod, Boolean copyMethodPtr) in /home/runner/work/Il2CppInterop/Il2CppInterop/Il2CppInterop.Runtime/Injection/Hooks/GenericMethod_GetMethod_Hook.cs:line
And after I set ListeningLog to false, I can enter the game normally
But as soon as I installed the AutoTranslator plugin, launching the game became impossible. It gave the following error:
[Error :Il2CppInterop] Nested type ToolbarButtonSize on GUI not found!

Here is my log file:

I copied your log for readability.

This seems like an issue with the plugin, rather than Il2CppInterop.
