Problem While other keys, (like z), work fine, the <leader> key (space) doesn't work at all!

I'm new to NVim, so, maybe, i haven't configured some key at the NVim config (haven't touched it, only worked with lazy), but i don't really know what's the issue here.

Please help!

You have to configure your mapleader BEFORE loading lazy
