problem with the camera

I am using a lenovo thinkpad and windows 10. If I try a version higher of 5.10.4 camera switch on by the image remain black. I was fine with 5.10.4 but beginning of the last week this version was discontinued. To use I need to make the connection through the browser and not the client. This is not nice. Throubleshooting information I was able to find are simply too trivial and obvious, so unuseless. Any help to solve the problem ? Camera work perfectly and led is switch on when activate zoom session, only image is not captured properly by zoom.
