It does not matter what sketch I try to compile, my pri will go into 100% CPU usage and hang. Even with the bare minimum sketch.

Ant idea how I can start debugging

Which version of the Arduino IDE are you using?

It says Arduino 1.8.8
I'm running raspbian stretch, updated and upgraded.
The only thing else running on the arduino are the vnc service and thingsboard iot server with the postgres database.

I am fairly new to the arduino/linux world so not sure if there is any kind of build in logging that can show what's going on when the vncscreen/IDE freezes.

Once frozen the rpi will stay on the wifi but I can not reach or via vnc anymore

When running the GUI do you see a yellow lightning bolt on the top right? This indicates a bad power supply which might cause freezes when the CPU is under heavy load.
