So I just wanted to get 100k on Nightfall the Ordeal but It crashed. I was confused On why it did that but It did do that before when I ALT Tabbed. Although It crashed, It was still playing in the background and i could not get out of game tab even though it wasn't there. I restarted my computer and proceeded to get back onto destiny 2 and play again. I hopped onto nightfall the ordeal and I played till the Shielded OGRE Bit on Nokris. (This Has all been on The Nokris Nightfall). I crashed at that point again. I was very frustrated because this time My screen just went black to the HDMI Screen. I was confused again because my computer was still running and the HDMI cable was plugged in. I restarted my computer again and tried to play nightfall again but to no avail, It crashed and my screen went back to the HDMI input screen. I have no Idea why this is happening and need help!
