Getting a crash on the following line

```
if (StudioSystem[Type])
{
    verifyfmod(StudioSystem[Type]->release());
    StudioSystem[Type] = nullptr;
}

```

specifically when calling verifyfmod(StudioSystem[Type]-\>release());

Disabling “Enable Live Update” in the Fmod settings in the UE fixed this problem for me.
