1.19.2 BYG crashing at startup

[Lavendie]

I've tried multiple different Forge and BYG 1.19.2 versions and always seem to get this message. Unsure if it's an incompatibility problem with another mod or what. Anyone able to take a stab at what I've messed up?

        java.lang.IllegalStateException: Config errors were found:

The error you posted suggests there is an issue with the byg config file. Specifically for the "byg:mangrove_sapling" in "C:\Users\among\AppData\Roaming\.minecraft\config\byg\trades.json5"

It's likely you have some configuration for a different version of minecraft or byg if you have been switching versions.

You should ask the byg mod author how to fix it.

 

Alternatively, you can try backing up the file and then deleting it. Usually if the file is missing, the mod will recreate it with default values.
