"Defiant Few: Go To The Source" weapon pick up bug

[EmbersToAshes]

System: PS4
PSN: EmbersToAshes-
In-game name: EmbersToAshes

For the mission "Defiant Few: Go To The Source" I am unable to pick up the experimental weapon. My character only seems to be doing the animation of picking it up and gets stuck doing it untill I get downed or press start and load up the start menu and back out of it.

Update: All experimental weapons in the map are unable to be used as well.

Update #2: All Arenas seem to messed up. Rip

Solutions I've tried:
1. Restart the app.
2. Abandon mission.
3. Restart my PS4.

None of those have worked.

Side note: in the video the server lags but that is not the cause of the bug. It was happening before the server lag.
