Fireworks Crash the Game + Incorrect Smoke Texture

I was making a Fireworks show in 1.21.4 on my Minecraft NYC Map, but noticed when I tested out a Firework with an actual pattern, not only was the Firework Rocket's smoke texture was horrible looking, using textures from various things but the Firework pattern itself crashed my game when it went off, I posted the issue on Reddit, and someone else was having the same issue
