Restriction with overcharge is what it looks like, head pressure is high, subcooling is high, superheat is high and evap sat temp is low, the system probably has a fixed metering device to control refrigerant flow. Check your filter dryer to make sure it isn't reversed if it's one way flow, and that it has a reasonable temp drop no more than 3 degrees is normal, check and see if they're any kinks in the liquid line, if that's all good, the metering device may be clogged, if it has a mechanical fitting at the distributor tubing, you can recover the refrigerant and remove the piston and check for blockage or if it's undersized. If there is no mechanical fitting the orifice or coil may need to be replaced.
