Well here is also my story. I also got Error Code CE-34878-0 and freeze shit on my pro. First time i played i got at about 1,5 hours of playing - and again and again in next 2 hours. Crtical issue i had in last story mision, the freqnency was about every 3-4 min. And also here are my findings abut this. - Turning off boost mode didn`t help at all - Turning off HDCP didn`t help at all - Rebulding a database din`t help at all Still the same scenario. Only when i reduce resolution into minimal one from options menu (720 p) it helps a bit and i was able to play about 5-6 hours without a single crash. But try to play destiny 2 in this -blam!-in quality :( it`s a nightmare.
