Logitch HD Pro Webcam C920 doesnt work ( audio works, video doesnt)

[edufissure]

I have Virtualbox latest version with Guest Additions: Versión 6.1.10 r138449 (Qt5.9.5)
Host: Ubuntu 18.04
Guest: Windows 10 Pro Version 2004 SO Version: 19041.329

So some time ago it worked ok, but some version of virtualbox made a regression, and now it doesn work.
The camera is detected and sound and micro works ok in skype but video doesnt. I have tested also in Google Meet and Blackboard...
Camera works ok both audio and video in ubuntu ( without the VM started)

Any help ? I really need this to work from home in these covid times...

Thanks
pd: questions or problems should be adressed in the Guest forum or in the host ?

Start the guest from full power off, not save-state. Run until you see the problem happen, then shut down the guest from within the guest OS if possible. If not possible, close the Virtualbox window for the guest with the Power Off option set.

Please right-click the guest in the main Virtualbox window's guest list, choose Show Log. Save the far left tab's log, zip the log file, and post the zip file, using the forum's Upload Attachment tab.

Please right-click the guest in the main Virtualbox window's guest list, choose "Show in Explorer/Finder/File Manager". In the window that opens, zip the guest's .vbox file, and post the zip file, using the forum's Upload Attachment tab.

I use the Logitech Pro C920 webcam and I'm very happy with the way it works. It's a webcam with excellent image quality...
