Problem with floor generator.

Hello everyone. So, im trying to do an endless runner, In order to achieve this, i have created some prefab cubes(that is a floor in this case, because my player moves on it) that are generated as the player moves, and of course, the cubes that are behind the player get erased. The problem that im having is that once my player exits one of the cubes and, enters the next one, sometimes a collision gets triggered, that if the player is moving fast, sends him flying away or bugs it.

I really dont know what is happening here. I´ve tried making a physic so that the ground has no friction nor bounciness However this still happens. What could possibly be? thanks,Hello everyone.
