No video camera detected

Hi!
My notebook camera and a webcam does not detected in XSplit Broadcaster v.3.9 9 (“Device is not available”).
In other programs, like Skype, Zoom, Windows Camera, they works and the cameras does not in use for them when I start XSplit.
This is happening since the last update of Windows 10.
I would not like back to the previous Windows 10 update, so any ideia about what is happening?

Thanks
Dalton
