Does plugging in a mouse/keyboard work?
If so, log in, go to Device Manager, right-click them and uninstall them both, then restart the device (it should install generic drivers).
If it still doesn't work, go to cmd, open as administrator, search for sfc/scannow, and wait for it to be done. Restart the PC.
Worst case, boot the laptop, hold shift, and press "restart," keeping shift held until the troubleshooting screen shows up. Go to troubleshooting and try a restore point.
If not it may be best to backup and factory reset
