Prism Launcher version: 9.4
Java version 21.0.7
Fabric 0.17.2

After installing Octolib and Immersive UI 0.3.3 ("Port to 1.21.8 :P") game crashes. After removing both, game works fine.

[07:45:36] [Render thread/WARN]: Removed resource pack immersiveui from options because it is no longer compatible

Hello, here it is: https://pastebin.com/DAq8AjpT

The error happens during fabric-screen-api-v1$onRenderScreen, which is exactly where ImmersiveUI hooks into rendering

java.lang.IllegalStateException: already at the bottom of the stack
at org.joml.Matrix3x2fStack.popMatrix(Matrix3x2fStack.java:117)
...
at net.minecraft.class_757.wrapOperation$cpg000$fabric-screen-api-v1$onRenderScreen(class_757.java:5923)

gonna look into this, thanks

fixed with 3b5b602
new version should be up in a couple of minutes

Now that was fast! Amazing, it works great, thank you! :)
