What happened?
A bug happened! My “iris” shader crashes, but the game starts fine after uninstalling!
I want my game to launch normally!

Steps to reproduce the bug:

Use the HMCL-3.6.11 launcher
Install 1.21.3 + Fabric 16.0.8 + fabric API - 0.106.1
Start the game in the same environment as me and observe the phenomenon

Minecraft Version
Minecraft 1.21.3

Iris Version
iris 1.8.1

Operating System
macOS 14.7.1 (23H222) on MacBookPro17,1 (arm64)

What is your GPU?
Apple M1

Additional context
The game throws 'ExceptionInInitializerError' on initialization
The error involves a failed Mixin conversion of the 'net.caffeinemc.mods.sodium.client.render.immediate.CloudRenderer' class.
It may have something to do with Shader loading or Mixin configuration.

In fact, I used a genuine Microsoft account to launch the game and downloaded the mod from the Iris official website I hope you can take users' issues seriously and not conclude without verification that they are using pirated products

You're using Iris 1.8.1 and Sodium 0.6.0-beta.3.

You need to update Sodium. https://modrinth.com/mod/sodium/version/mc1.21.3-0.6.2-fabric

[HarryH2O]

Thank you very much for your method, but after I updated "Sodium" and its related mods, the HMCL launcher sent me an unknown error related to a graphic error. I suspect this may still be related to Iris.Please you review my error report.

Here are the relevant questions I have summarized using AI and inferred based on my own experience, which may be helpful to you!

The Java application encountered a fatal error, causing the Java Runtime Environment to crash. Here are the key points from the error analysis:

Error Type: SIGSEGV (0xb), which is a segmentation fault. This typically indicates that the program attempted to access a part of memory that was not allocated or is not accessible.

Error Location: The error occurred in the glpLLVMGetFunctionGlobalVariableUse function within the libGLProgrammability.dylib library. This suggests that the issue may be related to OpenGL or a related graphics library.

Java Thread: The error occurred in the "Render thread," which is typically associated with graphics rendering.

Stack Trace: The stack trace shows multiple calls to libGLProgrammability.dylib, further supporting the assumption of a graphics library issue.

System Information: The application is running on macOS 14.7.1 with an Apple M1 chip. The system has 8 GB of memory and 8 cores.

Java Version: The Java version is 23.0.1+11, which is a relatively new version.

Possible Causes:

Graphics Library Issue: Since the error occurred in libGLProgrammability.dylib, it could be a bug in OpenGL or a related graphics library.
Memory Access Issue: Segmentation faults are usually related to memory access problems, such as invalid memory references or uninitialized pointers.
System Compatibility Issue: Given that it is running on an Apple M1 chip, there may be compatibility issues related to this architecture.

https://shaderlabs.org/wiki/Shaderpacks and the Vanilla Plus website, CF page, and MR page say that the Vanilla Plus shaderpack does not support Apple Silicon (ARM64, M1)

[HarryH2O]

So is there a solution? If not, I apologize for disturbing you

The linked website shows you which shaderpacks support Apple Silicon GPUs
