I had to look online to see if the 2021 model had a "barn door" or a slider.
My front bath door is a slider like yours but I have not had any issues with it.
Here a thread about the sliding closet door - very similar to your bathroom door (screen shot pic below). I was looking for one with photos to show the fix but came up empty. Maybe someone here will have better information.
