MVN Live Not Streaming Properly to Unreal Engine 5.6

I am currently experiencing an issue when trying to connect MVN Animate Pro 2025 to Unreal Engine 5.6 via MVN Live Link and live link hub.

The subject appears in the Live Link panel, but shows a warning icon and does not stream motion capture data correctly into Unreal.


Have you figured out yet?
Same here, UE5.6 + MVN Pro 2024.2 streams for a second, then stops with Subject is invalid

** seems to be sorted with solution in LiveLink settings from here
