You need to remove the touch calibration settings. These are going to be unique to your display. The other thing is typically a touch calibration will only need to be done when using a resistive touch display and the FT series of IC's are for capacitive type touch displays. It is very rare to need to do a calibration on this type of display IC.

I would add some kind of a check to ensure the user has WSL and if it is not installed output an error that states using WSL is required. I would also have a check done to make sure the WSL image that is being used in Ubuntu since Ubuntu is known to be compatible with the build system in lvgl_micropython.
