Thanks, but the problem is that an EpocCam driver is coming at the first option, and this is a driver used to connect my phone. So, it keeps waiting for the phone to connect and I cannot find a way to disable that driver or even uninstalling it. In google meet you have the choice to select the camera from the configuration menu.
