This seems to be a bug where if there are too many Ammo drops on the ground and a companion's Vacuum picks it up it may get stuck in your Warframe's torso, Playing the pickup sound on repeat and disabling your ability to interact with Life Support, Capture target etc, Tested this with Mesa, Saryn and Volt, Very consistent with when the Companion tries to pick up too many at one time.
Companion used was both a Dethcube with Vacuum and a Carrier Prime with Vacuum.
