HDCP suddenly not working

HDCP suddenly stopped working and therefore awful quality in disney+ (below 720p) and just 1080p in Amazon Prime and Netflix. Edge and Intel Graphics Software both say the internal Display is unsupported, but it should be and I'm pretty sure it has been in the past. Intel software says the external display is supported, but edge says otherwise and the resolution is still awful. I think it may have been the second to last BIOS update that was around the same time as this happened...Tried reinstalling the Intel Drivers, but didn't change anything. Any ideas? Does anyone have HDCP problems?
