My Xbox Series X keeps giving an overheating message, but it isn't even warm and was only...

I bought an Xbox Series X in winter 2020 and mostly play Warzone on it. Within the past few months it has begun to randomly crash during the middle of gameplay (always Warzone), and when I turn it back on, it gives me a message saying the console was automatically shut off to prevent damage from over-heating.

But it doesn't make sense to me... For example it just happened again a few moments ago, and I had only been playing for about 5mins total. My Xbox was completely cool to the touch, the fan didn't seem to be spinning, and it wasn't showing any signs of running hot.

Does anyone know if it's possible the Warzone game itself could be crashing, and then "tricking" the Xbox into thinking it overheated? Almost like the game itself is crashing my console, and the console just gives me the "overheating" message when I turn it on because that's what it defaults to? Or does it not work that way?

If anyone has input, advice or suggestions I'd greatly appreciate it!

I should mention that it's in a completely open area on top of my desk and there's no visible dust so I don't think it's a ventilation problem.
