Additional context
I already tested the mod on singleplayer and it works fine even with rubidium. But, when using it in a server, the client crashes but for some reason the server is still online.

java.lang.NullPointerException: Cannot invoke "net.minecraftforge.server.permission.handler.IPermissionHandler.getRegisteredNodes()" because "net.minecraftforge.server.permission.PermissionAPI.activeHandler" is null

@yahi-ko Do not assign random people.

tried with Armourer's workshop only on both client & server
crash report from client: https://pastebin.com/Vb56ztES
it didn't crash the server but I can give you the latest log
I don't think it would be of any help tho. but here is the latest log of the server: https://pastebin.com/Sgtp7abR)
