How do I get this sprite to stop disappearing?

Hi, I expect there's a really simple to solution to this but I've been stuck for hours because of it (still very new to this). I'm in the very early stages of making a game where the player sprite moves constantly to the right, but after a few seconds, it disappears - can someone please explain why, and how to fix it?

what is happening is that when you move the ground (Block) forward, the car moves with it. Then the car eventually falls off the ground.

you can see what is happening better if you set the Layout scale to 0.5 in the Start Of Layout event (event 1).

either make the ground invisible and stationary - and just have the scenery move past, or spawn new ground to move on to the screen.

I updated your file to do the latter...
