The new version is broken... please fix this

Balm crash.txt

With all due respect, this version of Balm is absolute garbage. I never had these issues with the previous versions, but now it's crashing the entire game just because it can't save a config file? Seriously? This is unacceptable for a mod that's supposed to be a core library. The older versions worked just fine this one is a huge downgrade.

Caused by: java.nio.file.FileSystemException: \AppData\Roaming.minecraft\config\balm-client.toml: El proceso no tiene acceso al archivo porque está siendo utilizado por otro proceso

The config file is being used by another process. Make sure no other processes are accessing the config file and try fixing your attitude.
