please help!
 

Hi,

The error complains about node N01035. Did you highlight this node and validate it?

Btw: don't connect output node LO to GND. Never do this with outputs.
In your case you need LO to charge the bootstrap capacitor.
You will find many discussions, threads, application notes what you need to take care when using high side only.
