Ancient Aqueduct: Lara FREEZES?

I'm on my first play through of SoTTR, i just completed the challenge in the Ancient Aqueduct. When i get back to my camp, i head back to where you see a mini cutscene of Lara putting back the gun she found before entering. when i proceed, my screen goes black then comes back on, for Lara to be frozen!? her guns/arrows all work, but not her movements?

i don't really want to restart the whole game again, is there a way to fix this? it just seems to be that area. I'm on ps4.
