I noticed that you are using the Cloth Config API v10.0.96 for Minecraft 1.19.4. The version for Minecraft 1.20 is not released yet, but you can try the v11.0.98 for Minecraft 1.20-pre6. With it, you should be able to open the seedcracker GUI without any problems.
When trying to enable GUI, the game crashes instantly.
Error Code:
The game crashed whilst ticking entity Error: java.lang.NoSuchFieldError: field_22735 crash-2023-06-08_10.34.36-client.txt
