There could be a few reasons why your webcam is not being updated. Here are some possible solutions you can try:
Check your device's connectivity: Make sure your webcam is properly connected to your computer and that it is turned on. If you are using a USB webcam, try unplugging it and then plugging it back in to see if that fixes the problem.
Restart your device: Sometimes, simply restarting your computer or device can help resolve issues with webcams.
Update your webcam drivers: If you have not updated your webcam drivers in a while, it might be worth trying to do so. You can usually find the latest drivers for your webcam on the manufacturer's website or by searching for them on the internet.
Check for malware or viruses: If your webcam is behaving strangely, it is possible that your device has been infected with malware or a virus. Run a virus scan to see if there are any threats that need to be removed.
Check your webcam settings: Make sure that your webcam is selected as the default input device in your device's settings. You may also want to check that the webcam is not being used by any other applications.
If none of these solutions work, it is possible that there is a hardware issue with your webcam. In this case, you may need to consider replacing it.
