is it open source?

Hello.
Love the mod, but one issue I am having is that most of the cars in the mod menu to spawn keep despawning nearly instantly.
Made sure I had the latest GTA5 installed. We re-downloaded scripthook and Elegance mod. We also now have Menyoo trainer also installed. Same thing with that trainer. Any recommendations of what I am missing? New to modding GTA5 so, sorry that I couldnt find the answer when searching. Found multiple videos of the issue but they state to make sure we have the recent trainer and/or to just switch trainers which also hasnt worked.
Sorry for being a noob.

Same problem as SketchyUnicorns, some cars (if not most) despawn nearly instantly after spawning them. It's a fresh install and everything else is working just fine.

This is literally just a Menyoo reskn

Menyoo but shitter, terrible design that doesnt load, off center, of course its compatible with menu xml when it is menu, fucking skid get a life.

What is the difference between yours and menyoo? Can you add a vehicle generation function that only displays DLC vehicles? Menyoo displays all vehicles by default, which makes it very troublesome to find the vehicles you added.
