[2021] The raider arena daily op breaks audio when against robots

i was doing the daily op and every time I'm on the watoga raider arena and against the resilient robots my audio just gets destroyed, it slows becomes extremely loud and when you're done the op and try to close fallout 76 it blackscreens and you have to shutdown, I'm hoping this isn't just a bug with me or my computer but its the second time I've done this daily op and had this exact same glitch. I've done it against mole miners and had no problem. It only seems to be against robots
