This has never happened to me since the beginning of D1. Since the launch of this season, Destiny 2 has completely crashed and closed the whole game, returning me to the Xbox dashboard. This has now happened twice in Gambit, resulting in me getting warnings for leaving early, It's happened a few times in Raids, once in Iron Banner and a moment ago while attempting my 1st Solo Duality Run.
Anyone else experiencing this issue. I cannot see any comments on this in the known issues on TWAB.
