What I have seen is, that if you stream from a PC to an Endpoint through UPnP or in my case Devialet AIR and the Screen goes in Energy Save mode, I had loss of connection of JRemote and Devialet AIR. MC and Devialet AIR or UPnP consume <1% of the CPU 8C16T during playback. It seems that Windows 11 put some services to sleep when the screen goes to Energy Save Mode?
