Iris Shaders: Failed to get entry for Block ID (block.properties Crash)

What it looks like in the log

java.lang.IllegalStateException: Failed to get entry for <so>

How to fix it

  1. Update Iris Shaders to the latest version available for your Minecraft release, as newer Iris builds handle stray backslashes and invalid entries in block.properties without crashing.
  2. Update your active shaderpack to its newest release in case the author has already fixed the syntax mistake for Minecraft 1.21+.
  3. If the game crashes immediately when loading a world or switching packs, open .minecraft/config/iris.properties in a text editor and change enableShaders=true to enableShaders=false to bypass the broken shaderpack.
  4. If you are maintaining or fixing the shaderpack yourself, open shaders/block.properties inside the shaderpack, check the invalid character shown in the 'Caused by:' section of your crash report, and remove any trailing backslashes (\) that precede empty lines or property assignments.
