My touchscreen PC monitor does not work any more.

My touchscreen PC monitor does not work any more. My touch screen monitor was working for years but one day just did not response when I wanted to use touchscreen. If any one have any ideas what went wrong or know to fix the issue, please let me know.

This is my  PC model HP pavilion all-in-one PC 24-b017a.

 Thank you so much.

Have you run diagnostics?
Tap the ESC key after powering on and press F2 to run diagnostics.

If the touch screen works during diagnostics then the problem is the windows drivers.

If it only working during diagnostics then bring up the windows device manager and look for error icons such as
