I Made A Huge Mistake In My First Ever Mass Sprint! (Zwift Racing)

In this video I ride the Crit Club DURA-ACE stage 4 race on Zwift! The stage is pretty flat, so getting away might be difficult. This seems to end in a mass sprint, and my first ever at that! I get to the last kilometer but then I make a HUGE mistake. Will this cost me the race? You'll have to find out! I also bought a new fan and follow your suggestions to lower in gear so my cadance is higher. This should make me less fatigued throughout the race.
