Default Recharging AC Low side high psi

AC wasnt blowing as cold as it used to so I purged the system and replaced the drier. I vacuumed the system. Opened one 12oz can of R134a on the low side. Turned on the AC to suck in the rest of the bottle and low side pressure when way up.

Low side pressure is 110. High side is at 100psi. I can hear the compressor click on/off. High side jumps from 50 to 100psi with comp. What happened?
