Hi, so I've been having a problem getting Minecraft to load with this mod in Fabric as the loading process crashes each time I use the mod. All I have in my mods folder are Fabric API and the Custom Blocks mod. Here's my crash report of when I tried to use the mod.

• Mod Version 1.3.0
• MC Version 1.17.1

The painting JSON you used must not be a valid JSON file. Make sure the files used are valid. A useful website to validate JSON files is https://jsonlint.com. I will make it so instead of crashing, it doesn't load the Custom element
