Help/Support Hooking function cause crash

[Batch 8k iPhone 7 15.7]

So im hooking to the update function, but everytime when it execute it crashes. Any idea?

void(*old_Update)(void *instance);
void Update(void *instance) {

    bool isHeroTurn = *(bool*)((uint64_t)instance + 0x2B);

    if (isHeroTurn) {
      //do smth
    }
 
    old_Update(instance);
}

void setup() {
  MSHookFunction((void*)getRealOffset(0x1B9D454),(void*)Update,(void**)&old_Update);
}

[Token(Token = "0x60006D9")]
[Address(RVA = "0x1B9D454", Offset = "0x1B9D454", VA = "0x1B9D454")]
private void Update()
{
}

[NonSerialized]
[Token(Token = "0x40004D1")]
[FieldOffset(Offset = "0x2B")]
public bool isHeroesTurn;

Make sure you set targeted it if using UnityFramework

Try this

void(*old_Update)(void *instance);
void Update(void *instance) {

    bool isHeroTurn = *(bool*)((uint64_t)instance + 0x2B);

   if([switches isSwitchOn:NSSENCRYPT("Switch Name Goes Here")]) {
    *(bool*)((uint64_t)instance + 0x2B) = true;
    }
 
    old_Update(instance);
}

void setup() {
  MSHookFunction((void*)getRealOffset(0x1B9D454),(void*)Update,(void**)&old_Update);
}
