DMX Channel Monitor Not Receiving Art-Net or sACN Data in Unreal Engine 5.7.4 (Works in 5.6)

Engine Version: Unreal Engine 5.7.4
OS: Windows
Project: New blank project using the provided DMX example content

The DMX Channel Monitor in UE shows no incoming data when receiving DMX universes via Art-Net or sACN over the network. However:

  • Data is clearly visible and active in dedicated tools like sACNView and ArtNominator on the same UE machine.

  • DMX is being transmitted from another computer on the local network over ethernet to the UE PC (confirmed working in monitoring tools).

This works perfectly in UE 5.6 under identical conditions, pointing to a potential regression or bug in 5.7.4 related to network DMX input on Windows.

Anyone else facing this?
