Only 1 instance of MetaXR simulator staring in MP mode

After updating Meta XR Simulator to version v81 - only 1 instance of MetaXR simulator staring in MP mode, but previously on v 78 (if i set "2 players" and "listen server") it starts 2 windows of Simulator.
UE start TWO windows (for both players) but Simulator only ONE.
How to fix it?
