My hero move without I touched it

Since some days, my hero (no matter who) move without I touched it and it’s so annoying when I want to play, does anyone have a solution ?

Enabling the High Precision Mouse Input option should fix this.

You can find this here:
Options > Gameplay > Scroll all the way down > Set High Precision Mouse Input to [ON]

Do you have other input devices plugged in? Like a controller or wheel. Maybe they are on and are getting an input.
