Simulacrum unplayable after 0.2.1b patch (console)

I can’t get through 3-4 rounds of simulacrum without the game crashing. I tried mapping and other bosses all fine to play so far. Mind you this was all solo play I can only imagine how much worse it will be when I try to party with friends this weekend. It don’t matter the build or situation it will crash. Never had this issue until after this patch, maybe one crash few weeks before but multiple times in one run makes the game mode nearly unplayable. I’m begging you guys to look into this and fix it. There’s already such small player count in end league which makes trade league so much harder I really don’t want to have to quit the game because of the end game modes becoming unplayable.

Having the same issue with Simulacrum, as well as a few maps like Oasis/Steaming Springs. This is not the issue with instances going into a forever loading screen. This issue force closes you to the xbox home screen. My friends that also play on xbox are having the same problem.
