Nami Burn e won’t turn off

My new to me Nami Burn e will not turn off from its power on/off button. It still runs as normal but the speedometer is stuck in 8.9 mph even when scooter is parked and the odometer stopped counting. So the power button does nothing when I press and hold it to shut it down. This happened after I went off a curb into a street…not at high speed and not a big drop.

Any suggestions?

This is a Nami Burn e Viper with following: Gen 2 display 50ah battery
