MatrixStack Underflow Crash (NoSuchElementException in ArrayDeque.getLast)

What the log looks like

java\.util\.NoSuchElementException\s+at (?:java\.base/)?java\.util\.ArrayDeque\.getLast\(ArrayDeque\.java:\d+\)\s+at net\.minecraft\.class_4587\.
java\.util\.NoSuchElementException\s+at (?:java\.base/)?java\.util\.ArrayDeque\.getLast\(ArrayDeque\.java:\d+\)\s+at net\.minecraft\.client\.util\.math\.MatrixStack\.

How to fix it

  1. Look at the line immediately below class_4587 or MatrixStack in the crash log for a Mixin tag formatted like handler$xxxxxx$modname$ or redirect$xxxxxx$modname$ (for example, $iris$ or $raised$).
  2. Verify that the mod named in that Mixin tag matches your exact Minecraft version down to the patch number (for example, do not run a 1.18 build of Iris on Minecraft 1.18.1).
  3. If the mod shown in the stack trace matches your game version, another client mod earlier in the same render pass popped the MatrixStack without pushing it; check recently updated HUD, chat, or controller mods (such as Controlify or Raised) by disabling them first.
  4. Update or downgrade the offending rendering or HUD mod to a release confirmed compatible with your exact Minecraft version and other installed UI mods.
