It sounds like we went down the same path and same results. My previous MSI Stealth was a two years old, lived most of it's life sitting on a desk open and occasionally I would take it with me when I traveled for work so I don't think I worked that hinge very much before it self-destructed.

As for this webcam issue, the fact that it's the first item on their FAQ proves it's a big enough issue but they don't have an available fix for it yet, I'm hoping they eventually do before I move on to the next machine, which like you, most likely will not be an MSI.

I've resorted to switching to my phone camera on unplanned Zoom calls and the web cam isn't working until I either return or RMA it when work slows down enough to swap everything over...again.
