Switching screens in touch screen mode on laptop

So when I am viewing a class on zoom and a teacher switches from camera mode to screen share mode and vice versa, if my laptop is flipped into touch screen mode it will bring me to the start menu. Every time I have to manually switch it back which can be annoying and I don't know if this is to do with my laptop or zoom but I would appreciate it if anyone knows a way to stop this from happening.
