Need Electronic/PCB Layout Expert

My PCB is not working - I'm overheating the buck converter for some reason.

It's for a device to control heating in 4 zones. Powered by DC around 45-55v. Temperature monitored by 4 x DS18b20+, rotary encoder for menu, 20x04 LCD for display.

It could be that I've put something in backwards / upside down or my circuit design is itself bad. I'm stuck, and need someone to help me diagnose the problem - I'm at the very edges . Project was designed in KiCAD.

Review the circuit design and PCB layout and determine the problems, and suggest solution and any general areas for improvement.
