HDR brightness slider causing hard freeze

Nothing is responsive here. I enabled HDR, and it looked okay and then I touched the slider to see the effects and it hard froze. I force rebooted by holding the power button on my tower, and now I booted to the slider all the way down. If I try touching the slider it hard freezes. So now I'm kind of stuck with ultra dim display. Just installed gnome Nvidia variant this morning. Is there a workaround? Should I install KDE?
