The Toxin bucket is crashing the game and i cant even create a singleplayer world because one of the recipe isn't good

on which modloader? and when does the game crash? Can you sen me a crash log?

so i was using Modrinth and it crash when creating or loading a world but just to be clear i did found what was the issue and it was a conflict between your mod and some others optimisations mod that was sodium options api or something like that, so you might look into that but yeah it works now

a crash log would be nice

Modrinth is a launcher, fabric or neoforge are modloader
