The Canadian lost the rear of his AMR23 exiting the final corner as he attempted to finish his final flying lap after the chequered flag had been waved for Q1.
Stroll appeared to clip the exit kerb at the first apex to unsettle the rear axle, which projected him into the outside wall.
He made heavy contact to spin across the circuit and into the path of McLaren driver Oscar Piastri, who narrowly avoided the stricken Aston Martin.
Stroll radioed to confirm he was OK before eventually exiting the car.
