Cam and Mic fail after the last upgrade

When updating to the latest version available, the camera stopped SHOWING an image and the microphone does not detect audio.
I did a downgrade version of Zoom and it worked again.
With the new version, the camera led lights up but there is no image. In addition, the camera works correctly with other applications. Something similar happens with the microphone.
The camera and audio drivers are up to date and in Win security, zoom is allowed to access the camera and microphone.
I have uninstalled and reinstalled the Zoom app with no positive results. I rebooted the notebooks on every install.
The same thing happens in another notebook of another brand. Both with Win10 with all patches updated.
