my xbox series x's hdmi port just randomly stopped working when i was having problems with...

I had the same / similar issue with my old 4K 60hz none HDR / HDMI 2.0 monitor when watching movies and some times in games with the Series X,

As soon as i upgraded my monitor to a 4K 144hz monitor that has HDR / HDMI 2.1 ports, i no longer had this problem,

I'm not sure what the problem is, but my guess is that the HDMI 2.1 port on Series X doesn't play well with HDMI 2.0 port of monitors, or it's the Series X trying to force HDR on, even if the monitor does not have / support HDR and the HDR in Series X menu's is turned off.

The keyboard itself plugs into my controller and the usb, I have plugged into the usb port on the front of my xbox series x. When using the keyboard, the keyboard works but the mic stops working.

And what if I buy a cable will it work

The Xbox Series X will come with a HDMI 2.1 cable,

But whether you use a HDMI 2.1 cable or not, the HDMI port on the TV needs to be HDMI 2.1 to achieve the 120hz refresh rates at 4K.

using a HDMI 2.1 cable on a TV port with HDMI 2.0 will still only limit the Xbox Series X to 60hz refresh rates.

I have not. I only have one 4k hdmi port on my tv and I don’t have another 4k cable to swap out. The same port and cable work with different consoles so I’m worried it’s an issue with the Xbox series x.
