Suggestion / Bug Platform

The compilation of a shaderfile of a texturepack fails.
It only occures in labymod. It happens with and without any addon, so its not depended by addons or farbic/forge.

Tested in Minecraft Version 1.20.4:
Vanilla: working
Fabric: working
LabyMod: failed

Logfile: https://paste.labymod.net/ufuhurilag (Error starts at 323)

If required contact me for a Test-Pack or the shader files.

Why is this required:

This type of shaderfile is required to change armor rendering for custom armor of minecraft servers. The loading of the pack failes in labymod, if this is included. would it be "not show" might not be good, but a timed solution. It would be great to get this fixed
