Game Crashes When Clicking 'Copy Info' Link in Chat (NullPointerException in mouseClicked)

What it looks like in the log

java.lang.NullPointerException @ mouseClicked event handler [net.fabricmc]

How to fix it

  1. Avoid clicking the '[Copy Info]' link in chat after a shader error; instead, open your '.minecraft/logs/latest.log' file directly to view the underlying error.
  2. Update Iris Shaders (and Sodium) to the latest version available for your Minecraft release so empty shader error messages no longer crash the clipboard handler.
  3. Switch off the failing shader pack in Options -> Video Settings -> Shader Packs, especially if you are on macOS using a shader pack that requires unsupported OpenGL 4.4+ features (such as Photon).
  4. If 'latest.log' does not show the full shader failure trace, open '.minecraft/config/iris.properties', set 'enableDebugOptions=true', restart the game, and check 'latest.log' again after reloading the shader.
