Had 2 different issues after dying while stuck in riot foam. The first issue was being unable to move after respawning. I was simply stuck in place- fast traveling to a different location had no effect. I had to restart the game. The second issue happened while taking over a control point. I went down and then immediately popped back up alive. I was unable to interact with anything in the environment except to revive the civilian leader. All enemies ignored me. Vid is only of the aftermath...I was next to the pillar/ammo box when it happened.
