MacBook Pro 13-inch 2017 Camera Not Working

Hello -

All of the sudden the camera on my computer is not working. Any ideas on how to fix that? The green light will blink or even turn on, but it's not capturing anything. This is the same across Zoom, FaceTime, etc. I tried restarting it, but it didn't change anything. Please let me know if you have any suggestions.

Thank you.

Chelsey
