System.AccessViolationException when injecting class

[jumbogram456]

After calling AddComponent, the type is successfully registered.

[Warning:Il2CppInterop] Class::Init signatures have been exhausted, using a substitute!
[Info   :Il2CppInterop] Registered mono type PokerServer.MyBehaviour in il2cpp domain

Shortly after, the game crashes and the error log contains:

Fatal error. System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
   at Il2CppInterop.Runtime.Injection.Hooks.Class_GetFieldDefaultValue_Hook.Hook(Il2CppInterop.Runtime.Runtime.Il2CppFieldInfo*, Il2CppInterop.Runtime.Runtime.Il2CppTypeStruct* ByRef)

The game is Vegas Infinite by PokerStars, I'm aware the game contains anti-cheat (only EAC) but I'm running the game without it (just by launching PokerStarsVR.exe) since my goal is to create a private server for the game. The game runs on Unity 2022.3.29f1.

I'm running this through the latest build of BepInEx which runs Il2CppInterop 1.4.5.

I've been temporarily able to resolve this by patching other methods in the game to get the callbacks I need (OnUpdate, etc), but it'd be much easier if class injection worked on this game.
