Game crashing in Delve

Playing an exsanguinate miner and my game has crashed 5 times now while trying to advance down in delve. It happens when I'm lighting the fires for the skeleton birds that charge at you. I can light all 4 fires and then it'll crash in the middle of the fight. Playing on series X.

Yup, happening to me as well.
THank goodness, the game pauses when you crash, so there is no death and thus no EXP loss.. it happened twice already, exactly whenever I do the Roah Nest Delve nodes.
EDIT: Also on Xbox Series X

Has been happening to me as well in delve. playing lightning trap of sparking.
