Hey,

when I am trying to get LuckPerms with the LuckpermsProvider it, returns null, same at the Registration Service.

https://github.com/lucko/LuckPerms/wiki/Developer-API#obtaining-an-instance-of-the-api

The LuckPermsProvider#get method won't return null. If it is null, it will throw an IllegalStateException, so I am a bit confused by you saying it returns null.https://github.com/lucko/LuckPerms/blob/0fd7f643a777f90b61c992454dd6dfe0151d3fcd/api/src/main/java/net/luckperms/api/LuckPermsProvider.java#L48-L53

Would you please send the error you are getting in your console?
