Bug description

When launching Ultimate Car Mod and its sister mod, Ultimate Plane Mod, the game crashes. With Neoforge. Can you make a Forge version?

Minecraft version

1.21.1

Mod version

car: 1.21.1-1.0.24 plane: 1.21.1-1.0.9

Mod loader and version

NeoForge 21.1.11/21.1.35 (latest supported on my launcher is 21.1.23)

Steps to reproduce

1. Launch the version where the mod is. (Neoforge)
2. See the error. Rinse and repeat ad nauseam.

Expected behavior

The game should launch and run normally with the mods.

Screenshots

No response

Works perfectly fine with the latest NeoForge and mod versions.

Unfortunately, I have trouble with the mod loader itself, it doesn't launch and sends me an error message. Mods are fine
