I recently washed my 2022 crf450r and after drying it wouldn’t start. When starting there is no power starting the engine but the kill switch lights up whenever I try to start it. The battery was not the issue when I checked it. I haven’t checked anything else.

The kill switch is usually just a switch that will connect one of the computer's (ECU) inputs to ground to signal stop. If you blasted something with a power washer, then you might have shorted something with water. Don't blast things with a power washer. They are designed for rain.
You might also have flooded the spark plug well so you are not getting any spark.
Sounds silly but is it in neutral? Dry the kill switch out. Also the crf are terrible at fouling plugs when run for a short period and shutoff.
It’s in neutral when I tried. When I push the start button I hear nothing. I’ve read that these CRFs would cut power to the starter if it doesn’t have enough current. I don’t know I ride yamahas and I’m trying to help my dad with this problem.
I’d start by try jump starting it, don’t have the car engine running when trying, or just use a good 12v jump box, there is a start sequence before it’ll crank, you should hear the fuel pump kick on to pressurize the injector, then it should crank, if it’s low on volts or amps, no crank
Try hitting the kill switch with an air compressor.
