Nintendo Switch quickly overheats when playing Mario Odyssey. Why?

My Nintendo Switch, which is now almost 3 years old, overheats very quickly when playing Mario Odyssey (only in the dock) so far this problem really only occurs with Mario Odyssey. For example, with Minecraft or other games, I was able to play without problems for over 2 hours without the switch overheating and switching off. When playing Mario Odyssey, however, it already switches to c. A 20-30m from. My question is Can there be a problem with Mario Odyssey's software or is it possible that the Nintendo switch is broken? I would send them for repair and have them checked, but that's a bit difficult right now because of the corona virus.

She endures Mario Odyssey with me for hours. See if there's dust in the ventilation slots from the switch. You can gently vacuum this out with a vacuum cleaner.

Clean and blow through the fan and heat sink with a paintbrush. Should help. I do on my notebook when I notice that the fan is almost flying around my ears.
