Black screen on building's second floor

[Brax]

I'm in march ridge's dormitory. Second floor.

I slept and when i woke up the screen went completely black as if i haven't any line of sight.

If i move a step, the screen returns to normal, another step redisappears and so on.

The game logs this exception non stop:

If i manage to move outside the building the problem disappears.
