CyberLink YouCam9 Deluxe might help if the issue is specific to the webcam hardware. It creates a virtual webcam so you can do things like reduce webcam resolution to 360p outgoing. Microsoft really should be improving it's webcam support and provide more customization, at least for their LifeCam line which had better advanced tools in Windows 7 OS than it does with Windows 10.
It's unfortunate that Zoom is still the best for meetings using a smartphone.
