i got the same issue. was working with previous windows, installed fresh windows, installed driver from site, and touchscreen just stops working. shows it working in device manager. im still looking for a solution.
Same issue too. A lot of people are dealing with this. Gpd have the win 4 to care about.
I tried every single driver found and many clean install. Nothing worked. I know it can’t be hardware… was working fine till fresh windows install. If someone have a workaround I’ll gladly take it.
