The game upon startup:

Looking around to the red rose:

Moving the camera some more:

After running and jumping for a bit I was able to open what I think was a door, though upon opening it the camera zoomed further and flipped upside down:

I do want to point out that the windowed screenshot was taken before I had realized I hadn't updated my NVIDIA driver to the latest version, so I did so hoping that would fix the issue, but sadly it did not, as the Fullscreen shots were taken post driver update.
I then wondered if validating the files through Steam would help, but this did not fix the issue (screenshot of this + Build ID. Have also attached .txt of dxdiag)

I have tried everything from rebooting in Windowed/Fullscreen, adjusting graphical settings, Vsync, etc but have no had much luck. Would anyone have any advice on how to troubleshoot the issue? Any feedback would be very much appreciated!
