Since yesterday, my game now crashes constantly in the Crucible (XB1)

The game crashes in 9/10 matches now! I have tried using (and not using) a range of different weapons and abilities to determine the cause but it seems to occur randomly. This only began yesterday and does not happen in PvE. I have tried reinstalling Destiny, to no avail. Is this happening to anyone else? Any solutions? It's ridiculously frustrating not being able to make it through a single match!
