This is the first time I've noticed anything like this. Maybe it's because I just watched Serial Monitor. But I've never had it in the SD card log either.
I'm taking on another useless project. And that's a wireless copy&paste&selectAll keyboard. The keyboard simulates pressing ctrl + c/v/a. Everything works as it should. My button are in INPUT_PULL mode, in the future I plan to replace the buttons with mechanical mx cherry keys. Simple circuit with even simpler code. Below I attach the wiring diagram, unfortunately it doesn't have esp32 in fritzing, but that shouldn't matter.
However, I sometimes get the button sort of pressing itself. I have a prusa 3d printer at home, otherwise standard equipment. Like the fridge, TV, washing machine. No microwave. But this interference, it comes even when everything is off, except the fridge, of course.
