Controller vibration problem

hey there, im having a bit of a trouble with setting up controller. the thing is. i can connect to the bluetooth controller but the rumble/vibration is abnormal. like it keeps vibrating and never stops even though my pc is idle.
my EOS is a fresh install. and used upgrade and update but nothing more than that. am i missing something?
it’s a switch controller btw the input works fine. The vibration and gyro sensors are the problem
