There is nothing on your system who could prevent a "fast" double tap ?
(like on Mac, there is option for enable a "timer" between tap and "action" in accessiblity settings for keyboard. I don't use it, but it's for avoid non-untended double taps).
When you had reinstall the game, you have deleted all the game files, there was really nothing left ?
