When loading into some worlds, this error spits out causing the game to hang without crashing:

[20:39:08] [Worker-Main-17/ERROR]: Using missing texture, unable to load minecraft:textures/0.png : java.io.FileNotFoundException: minecraft:textures/0.png
[20:39:09] [Worker-Main-27/WARN]: Unused frames in sprite gofish:item/galaxy_starfish: [5, 6, 7]

This is when using 1.4.1 for 1.18.1.
