Mine carts are glitching badly.

So ever since the updates came, my ride I’ve been working on was running smoothly. I was doing test cycles before opening. Unfortunately the update ruined the game and I was forced to shut down my ride until further notice. Is there a way that you guys can resolve this because I need to open this ride for 2024. It was supposed to be opened the summer. I attached a picture for proof. I hope you guys can fix the minecarts glitch. I used a / execute command and I connected 2 carts to a middle. Before the update happened, it was running, now it’s not.
