Windows 10: My Yoga C740's camera is showing black screen.

It's been a month since I am using lenovo Yoga C740. Experience is good so far. But today my webcam is showing black screen.

I used the webcam yesterday during video conference with my classmates but today it's totally black.

The settings are all OK and privacy is disabled. No virus detected. The device manager is saying the camera is working properly.

Lenovo Yoga C740 laptop

Hello, I am looking at a laptop with touchscreen right now and it's coming with 2 options of processors.

Lenovo Yoga C740 (15)| Build Your Own Laptop | Lenovo Canada

i5-10210U
i7-10510U

So I looked at some benchmark websites and these 2 processors don't seem to be very far apart, it's hard to tell how much faster the i7 could be.. So I wonder if it's really worth spending the extra 100$ for the i7.

It's mostly going to be a office computer, perhaps with small games.. web browsing, usual multimedia, I don't believe too much video and audio edition or any encoding, virtual machines..

would you consider that the i7 is much better overall, better value, or both are too close to spend the extra bill?
And do you have an opinion on these Lenovo Yoga computer with touch screens? Are they of good overall quality, nice screen? Just to get perhaps third party opinions

And finally if we think about graphics both use the Intel UHD and according to these websites, it's exactly the same thing except for the Max dynamic frequency the i5, it's 1.10 GHz and 1.15 GHz for the i7

Is it safe to roughly assume that on small 3D game, the polygons, both processors will provide about the exact same performance?
