These are classic symptoms of no direct connection of the GND
from the power supply to the micro. The second most common
cause of these types of symptoms is a broken/missing connection
that you are expecting to be low (like MCLR). Both a 0V and a no-
connect appear the same on the scope, so you start drawing the
wrong conclusions and then go into a hair pulling spiral.
Connect a 100k resistor between your scope probe tip and the 5V
supply (so it acts as a pullup) and recheck all the pins that you are
expecting to be at GND potential. If it's really connected, it will
appear low. If not, it will be high.
