Can't spawn car after restarting server

Hello, when i start my Server then i start my Client i can spawn anything i want with mod menu (enhanced reborn), but if i restart my Server and i don’t restart my Client, when i join session i can’t spawn cars (both types, normal GTA V default cars and modded cars).
How i can solve this?

Don’t restart your server while you are in it? :joy:

Before I restart the Server, I disconnect from that…
But I stay in FiveM menu (Server list), i think is not good to exit the game and restart every time i restart the server, because if I’m developing something I’ll restart so much more…
