Can you provide more information on the screen you are using?

How is it connected to your RPi4b?

What image is running on the Pi. Are you able to print via Mainsail/Fluid?

Welcome mcgearytech,

the phisical screen itself works fine the issue is with the bigtreetech vivid menu when i touch it i get the errors. thats the interface to work with my btt vvd mmu on my printer.

Please always attach the complete klippy.log.
We see the issue - we have to find the reason.

The issue is that in this KlipperScreen commit, the api layer was renamed from klippy to api.

This means that any occurance of self._screen._ws.klippy needs to be changed to self._screen._ws.api in any add on code.
