Hello there, I'm Gopal an Independent Advisor. I will try my best to help you.
Please try to disable and re-enable touchscreen Hardware and see if that helps
In the search box on the taskbar, type device manager, then select Device Manager.
Select the arrow next to Human Interface Devices and then select HID-compliant touch screen. (There may be more than one listed.)
Select the Action tab at the top of the window. Select Disable device wait for a few seconds and Enable the device again. If there's more than one HID-compliant touchscreen device listed, perform steps 2–3 for that one too.
Regards,
Gopal
