Blinker Test on a 16F18313

Hello,

I've just started to use a new PIC which I cannot get to work at all, I suspect it has to do with the OSC setting or the PPS setup.
To start with I'm just trying to flash a LED on RA3, in the long term I'll have TX on RA0, RX on RA1, and PWM on RA3.

Any help will be greatly appreciated!
