If you define code like the one below, you will get an abnormal disconnection when entering an instance.
[UdonBehaviourSyncMode(BehaviourSyncMode.Manual)]
public sealed class Demo : UdonSharpBehaviour {
[NetworkCallable]
public void R(string[] arr) {
}
}
This occurred not only with string arrays, but also with VRCUrl arrays.
This can be worked around by using VRCJson, but it would be nice if this could be fixed.
