Internal Webcam works fine and then becomes dark all of a sudden (Acer Aspire 3)
I have had this bizarre issue for the past month where every time I switch on my laptop, and use my webcam, it is completely fine. I'll have a skype call and it works fine, but if I have to reconnect with the call, my webcam suddenly becomes dark (almost pitch black). The odd thing is that the next day the webcam will work completely fine, but then have the same issue where it will get darker.
I don't understand what the issue is (how it can work and then get dark all of a sudden, and then reset?). I have tried to reinstall drivers and common troubleshooting methods for webcams that don't work, but my webcam does work sometimes.
If anyone could help it would be much appreciated. I'm using windows 10, and as I mentioned have an Aspire 3 laptop. I also teach online so a webcam is necessary for my work, so it's urgent, thank you!
