Crash when initialize callback class

[seedhollow]

When the IL2CPP Resolver is initialized, I attempt to use IL2CPP::Callback::Initialize();, but it unexpectedly crashes the game. Or maybe my implementation is incorrect.

// This is my OnUpdate method
void OnUpdate() {}

if (!IL2CPP::Initialize()) {
    Vars::Misc.isInitialized=false;
    LOGE(OBFUSCATE("Failed to initialize IL2CPP Resolver"));
}

else {
    Vars::Misc.isInitialized=true;
    LOGI(OBFUSCATE("IL2CPP Resolver initialized"));
}

IL2CPP::Callback::Initialize(); // crash when calling this
IL2CPP::Callback::OnUpdate::Add(reinterpret_cast<void *>(OnUpdate));
