Geckolib 4 error with Minecraft 1.20.1-forge 4.2.20

[dedonor]

My game keeps crashing due to rendering overlay and blames either geckolib 4 or azurelib, does anyone know a fix?

This is the error: https://paste.ee/p/X3tZ8

One of the mods has an invalid animation json - but this mod is not mentioned

Start with GeckoLib and AzureLib and the mods requiring it

If this works, add the rest of your mods one by one or in groups until you find the one, causing this issue
