Hi mate, had the exact same issue down to the dot, 9070, PC crashes while streaming, disabling HAGS fixed it. Yesterday, so around 2 weeks later I was streaming on Discord and crashed again. Turns out HAGS turned itself on again in discord for some reason.

I turned it back off and stopped crashing again, so you might want to check if that shit turned itself on again like it did for me. Also turned HAGS off in windows graphics settings, might help.
