Razer Blade 15 (2018) Advanced Camera and Mic Not Working

Hello, I have Razer Blade 15 (2018) Advanced model. I am facing an issue with camera and microphone. For some reason they stopped working. I'm not sure when that happened, because I haven't used them a lot. However, because of online learning, I started using them very often. They worked fine when I bought the machine, though there were some issues with the camera (some grey and green lines appeared when recording). I suspect it is something to do with the recent Windows Updates. I have Windows 2004 with the latest updates installed. I tried to delete and resinstall Realtek and camera drivers, but it didn't work out. What can I do?
