Windows 10 changed my webcam drivers and won't let me change back

I got a Logitech c920 webcam two years ago. Everything was fine. Then a while back, I started having issues with the camera. It would just suddenly go off during a Zoom meeting, or worse, it would switch to my laptop computer and show my crotch instead of my face.

When I open the webcam software, I get the message that I am using generic Windows UVC drivers and that I should install Logitech drivers (which is what I had originally).

When I try to change the drivers (not easy, since the Logitech drivers are basically hidden), Windows 10 tells me that I have the best drivers and it flat out refuses to allow me to change them.

Logitech tech support has not helped. I've tried to get them to send me driver software, but to no avail.

When you first plug the webcam into the laptop's USB port, the drivers install. But unplugging and plugging in doesn't help.

I have done some things that seem to work (and I apologize but now I don't even remember what they are). Then it tells me to restart the computer and I do. But I still get the same message from the webcam software. At the same time, I haven't experienced the webcam problem in a couple of weeks, so I'm wondering if I did something right. It's all very confusing.

Can anyone help me update these drivers to the right ones? Please keep in mind that I'm not a techie so if you use a lot of tech language, I might not understand it.

Thanks in advance for any help you can offer!
