CameraPreview's FrameArrived Event Inconsistent Firing

[DJRM2021]

Describe the bug

I'm using the CameraPreview control on a WASDK 1.2/WinUI 3 desktop application. I've followed all the documentations and the sample on the toolkit app. When I build and run my app, the CameraPreview does its job of previewing the camera live feed for 1 - 2 seconds, then afterwards, upon checking with the debugger, the FrameArrived event will stop firing. MediaPlayerElement is already present and working as of WASDK 1.2.230118.102.

The CameraPreview.cs file inside the toolkit needs to be updated to remove the TODO: WinUI3 commented-out-codes.
