[FTC]: Problem with init

We use Android Studio and sdk version 3.5 for our robot controller. The robot was working a week ago and we did not change anything. But now the robot suddenly won’t init. The error we get is “Unable to find a hardware device with the name.”:frowning: The robot cannot recognize any motor, servo, or sensors:yikes: Anyhow, the wiring is not changed, the motor controllers and power distribution module all work properly. The code is probably correct too. We cannot think of any other things that might cause this error. Could anyone help?

Here is our code

Thanks!
