Sure, I can help with that! Just to be sure I give you the best steps—can you let me know:
# ***What device is the camera on?*** (Phone, laptop, webcam, etc.)
# ***What exactly is wrong with it?*** (Not opening, blurry image, black screen, flickering, etc.)
# ***Any error messages showing up?***
# ***Operating system?*** (Windows, macOS, Android, iOS, etc.)
Once I know those, I can walk you through a fix that makes sense for your setup.
