Windows 10: miracast issues

so I was using miracast to use my TV as a second monitor without any issues and I had to restart the PC for some reason not an updatewhen it was fully open, I opened the cast, and tried to connect TV; my mouse was focused on the center, and the screen was frozen; after a few seconds, I saw the desktop on tv for 1-2 secs, and then it was gone and it said something above but I didn't pay attention and tried again; it said "couldn't connect" I tried it like 30 times and either said couldn't connect or the same thing happened. I nearly tried everything on the net but nothing workedversion: 21H2o

miracast issues

Already tried all the suggested "fixes"-----to no avail!

My opinion msft has changed something that caused miracast capability to go away in one of their many updates!!

When viewing device manager miracast was listed now its missing!!!!

Maybe it was unintended , maybe not!!

Im sick of msft tactics!! Ready to discard all msft products !!
