Hi, I'm Bernard. I'm happy to help!
Have you tried using an external mouse to check if the issue is on the hardware side? While waiting for your response, let us manually roll back the touchpad driver:
-Press the Windows key + X
-Go to Device Manager
-Expand Mice and other pointing devices
-Look for your touchpad driver
-Right-click and click Update Driver
-Select Browse my computer for drivers
-Click Let me pick from a list of available drivers on my computer
-Choose an old driver or another driver name, then select it and click Next until it installs.
-Restart the PC and check.
Note: If the issue persists, please download and install a touchpad driver and/or a firmware update from your manufacturer's website.
