What it looks like in the log
java.lang.IllegalStateException: max stack size of 16 reached
How to fix it
- Update Entity Model Features (EMF) and Entity Texture Features (ETF) to the latest builds available for your exact Minecraft version.
- Update ImmediatelyFast and Iris Shaders to their latest versions to ensure compatibility with recent rendering changes.
- Test the game after disabling resource packs that rely on custom entity models (such as Fresh Animations) in Options -> Resource Packs, as broken model definitions can trigger the leak.
- If the crash persists while loading chunks, temporarily remove EMF and ETF from your mods folder or toggle shaders off in Video Settings -> Shader Packs until an updated mod build is available.
