Central AC Low side is 500 PSI

Just turned on my Trane central AC and it's broken. When compressor's On, Low side jumps to 500 PSI and High side is a reasonable 225 PSI. When compressor turns Off, Low side drops to a reasonable 53 PSI & High side stays the same.

Evaporator coil is nice and cold at bottom. But top 2/3 is warm.

Any help on where to start looking ??
Thank you- Mark A.

Due to certification requirements we don't discuss a/c system repair here.
