The PSE is over, the items picked up, and here I am still stuck holding my arm up. The only thing I could do to escape it was leave party/abandon the quest. This has happened to me once before, on this map.
This happened to me while running floating facility VHAQ. I initiated the PB and held the button so others could join in. Afterwards, I was stuck in the animation, invulnerable. I could still pick up the nearby items, will post a follow up image showing time lapse, and the red items picked up.
