and I doubt your config setting is correct

it could go like this , but why would you

@MyConfig = _INTRC_OSC_NOCLKOUT & _WDT_OFF & _PWRTE_ON
@MyConfig = MyConfig & _MCLRE_OFF & _BOR_OFF & _FCMEN_OFF & _IESO_OFF
@ __config MyConfig

this is the prescribed way

#CONFIG
cfg = _INTRC_OSC_NOCLKOUT
cfg&= _WDT_ON
cfg&= _PWRTE_OFF
cfg&= _MCLRE_ON
cfg&= _CP_OFF
cfg&= _CPD_OFF
cfg&= _BOD_ON
cfg&= _IESO_ON
cfg&= _FCMEN_ON
__CONFIG cfg

#ENDCONFIG

or this

#CONFIG
__config _INTRC_OSC_NOCLKOUT & _WDT_ON & _PWRTE_OFF & _MCLRE_ON & _CP_OFF & _CPD_OFF & _BOD_ON & _IESO_ON & _FCMEN_ON
#ENDCONFIG
