Couple of things to check on. Serial out + ground are connected to the device you are sending to. You are possibly missing the ground. Second to check is decoupling caps on the circuit.

High likely one or 2 missing Vdd, Vss connections or a floating MCLR.
Could still be some weirdness from your crystal...

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

Re: What happens when I connect my oscilloscope to a circuit
You were both right, the ground line was missing from the terminal to the PC. It was on the schematic, but altium didn't update the board correctly for some reason. Thanks for the responses.
