You should not have a CAP directly on the MCLR pin.
It interferes with the timing of the ICSP signals
The resistor you left out, isolates it from the MCLR pin.
Typically, all you need is a pull-up resistor, unless your VDD rise time is slow and it need to stay in reset longer.

You must tie the ENVREG pin to 3.3V to enable the on-board regulator. With a CAP on the Vcap pin.



You must also have AVdd and AVss connected to VDD and Vss, even if your aren't using analog.
