Attempt to invoke interface method 'boolean android.hardware.usb.IUsbManager.isFunctionEnabled(java.lang.String)' on a null object reference

[mymedia2]

I installed Anbox on Ubuntu through Snap, activated developer options tapping Build Number 7 times, and then I try to open the developer options but Settings crash.
