Windows 10: Camera on laptop is not detected and i am now unable to make video meetings

All of a sudden the camera on my computer is not detected and i am not able to use my camera for video meetings. It says : Unable to detect a camera.

:)

 

How can I make my computer detect my integrated camera?

Not even the default windows 10 camera app can detect my laptop camera. I've looked online and they suggested checking device manager, but my camera didn't show up there either. Here's my computer hardware:
My computer specs. I have an msi laptop, but unfortunately, I don't know what the model number is because it isn't written anywhere on the laptop.

 

Zoom meetings

I am unable to participate with video on a Zoom meeting. I can get a still photo but it has a white camera with a slash through it. But, no video.

 

Camera not detected on my laptop, how to fix?

My laptop has a built in camera, and I wanted to join a Zoom meeting. However when I opened Zoom (and later tried this with other apps, like Camera itself) it said "Zoom is unable to detect a camera". The error message and code from the Camera app was:

We can't find your camera. Check to make sure its connected and installed properly, that it isn't being blocked by anti-virus software, and that your camera drivers are up to date.

Error code: 0xA00F4244<NoCamerasAreAttached>

Would appreciate any help on this matter. Thank you!
