Moonlight Client on Nvidia Shield Pro closes instantly upon start-up

Hi all, weird one this evening. Have just updated my Moonlight client on my NVidia Shield Pro and upon opening it , you can see searching for PCs for about a second, and then Moonlight closes. This is the latest version just pulled down. I have another Shield Pro in the lounge which is running an older version of Moonlight and that also instantly closes. Normally Moonlight is 100% , so not sure if something on my network is causing this issue, my PC running Windows 25H2. Any advice, thank you.
