Camera issue

Hi all, my Dell laptop camera was working seamlessly for a while, but suddenly it stopped working and shows only a black screen. I have tried to fix it by resetting and repairing it in the app settings, and also I tried to update the driver in the device manager, but still, it's not working. Additionally, it is not working for a Zoom call or anything, so I can't have a video call. Please, if anyone could help?
