Unresponsive touchscreen

[Molecular]

I have a HP Pavilion 21 Touchsmart All-In-One PC (Windows 11) that has an unresponsive touchscreen. I unabled and enabled it in device manager... Uninstalled and reinstalled it... Rebooted...Went through setup, didn't see a "touch device" there. Tried to calibrate but nothing happened. Went into the bios to do a component test....the screen only detects a few touches in the upper-left area of the screen. What else can I do? 🤔
