So basically i can't join my world and can't unninstall the mod.

When i try to enter my world my game simply stops responding for a long time, it didn't crash so i don't know if there'd be a log or something for that, and if i try to remove the mod it gives me this:

"Vampirism (vampirism) encountered an error during sided_setup event phase"
"java.lang.NullPointerException: The validated object is null"

Nvm the issue is me (i modified a config file from another mod)
