Idk if this helps, but I saw the error only happens with geckolib versions higher than geckolib-forge-1.16.5-3.0.97.jar.

With the geckolib-forge-1.16.5-3.0.97.jar my game doesn't crash with this error, but with the geckolib-forge-1.16.5-3.0.99.jar crash, i don't see the geckolib-forge-1.16.5-3.0.98.jar in the curseforge website https://www.curseforge.com/minecraft/mc-mods/geckolib/files/all?filter-game-version=1738749986%3A70886 so I don't know if the error started in the .98 or in the .99.
