Camera Issue (Shadow in the Corner)

Hi,

I have an Inspiron 7391 2-in-1 and the camera is not working properly. Whenever I open the camera, there is a big shadow at the bottom left corner, as if something is blocking its view. As a result of that, the whole picture is also darkened. I've tried to clean the surface on the laptop, and it did not fix the problem, so I think the problem is inside (perhaps that the camera is misaligned with the opening?). I'm not sure when the problem has started as I didn't start using the camera until recently (zoom meetings...) and it has become increasingly annoying. Please help me fix this!

Ps: Here's a picture I've taken with the camera of a blank, white wall with proper lighting.
