Touchpad not working and not detected when I run ‘xinput list’, on Ubuntu 20.04

I was typing a text when my touchpad stopped working. After surfing on the web to try to fix the error, I ran

xinput list

and here is the output :

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Logitech USB Optical Mouse                id=10   [slave  pointer  (2)]
⎣ Virtual core keyboard                     id=3    [master keyboard (2)]

    ↳ MSI WMI hotkeys                           id=13   [slave  keyboard (3)]

My touchpad seems to be not detected as it does not appear in the output.

Thanks for your help.
