Reproduction Steps

(Google translation)
Hello.
In the past 2 days, several mods have been updated:

• from "create-aeronautics-bundled-1.21.1-1.2.1.jar" to "create-aeronautics-bundled-1.21.1-1.3.0.jar";
• "sable-neoforge-1.21.1-2.0.0.jar",
  after which the game crashes (I provide the crash log files "block 1".
  After updating your mod (from "sodium-neoforge-0.6.13+mc1.21.1.jar" to "sodium-neoforge-0.8.12-alpha.4+mc1.21.1.jar") also causes the game to crash "block 2".
  I hope this will help identify the issue and fix it in future updates.
  So I've had to roll back some mods to keep the game running.
  Thank you for your assistance.

From what I can see in the logs and crash reports:

• For block 1, you have installed the last version of Sable (2.0.0) and Veil, which are both dependent on Sodium 0.8.12-alpha, but it's in 0.6.13.
• For block 2, Iris Shaders is installed, which currently doesn't support Sodium 0.8.12-alpha as per this issue or this one over on their repo.

I suggest removing Iris Shaders while it's incompatible, until it gets a new compatibility update with Sodium's alpha.
However, according to a changelog on Sodium's Modrinth page, Iris Shaders has a build on Discord that works.

Iris has been updated, but the build is still in unstable testing on discord. I'll see if we can change this.
