Hi @massimo81510
Check if the touchscreen has been disabled in Device Manager.
To get to Device Manager in Win10/11 press the Win key and the x key (both together) and click on the Device Manager link in the menu box that appears.
When in Device Manager, scroll down to Human Interface Devices → click on > to expand the list of devices → right click on HID-Compliant touch screen.
If it shows an option to enable device click on that and follow the prompts. Restart the laptop and check if the touchscreen works OK
