Cars spawning then disappearing

[Zoey]

After I updated my game, I used the trainer to spawn a car. like 5-10 seconds later, it just vanishes as I'm driving and I'm just standing in the street. Anyone having this problem or know a fix?

@Zoey I used this https://www.gta5-mods.com/scripts/mplowrider2-in-sp and this https://www.gta5-mods.com/misc/gta-5-gameconfig-300-cars

Don't know for sure if you need both to stop that but that's what I had installed to stop it.
