Laptop video/camera not working

[aidipi]

Looking for some advice please. The camera and video on my laptop have stopped functioning correctly. If i am on Skype or Zoom i can see other people but ot myself and they are unable to see me. All I get is a greyed out camera with a line through it. I am also unable to view some of my videos and photos in my files.
I ha e checked the camera and updated the drivers to no avail.
