I am also since Friday 17th experiencing black screens received over my home LAN for pc or Mac into OBS or NDI to Spout methods that have worked for months..no new updates,,,, or new settings... I am also sending using NDI outputs rom VJ software VDMX, which was working and now only black is at the other end - what is going on ? ( I have Intel MBP, M1 Mac 16 gig model and a NUC PC )
