Glad to hear that worked.
The 5.1 version of the plugin actually isn't compatible with Twinmotion yet, since it uses Unreal Engine 5.1 features and Twinmotion is only on UE 5.0.3, and that explains why those issues were occurring.
We'll be updating to UE 5.1 soon, so that plugin should be usable then. We'll update our plugin pages once that update becomes available.
Best,
Raghib
