Can't install Anaconda/Miniconda properly

Product Help Anaconda & Miniconda
1

So basically i tried to install anaconda or miniconda multiple times using different methods but nothing works as intended :

→ When i create an environment ( conda create --name “name” python=“python version” ) If i activate it it doesn’t have python, pip or any package it should have.

→ I wanted to use anaconda-navigator to manage it but it doesn’t start either, blocks on loading environment on the screen and in code i get an error :

QMimeDatabase: Error loading internal MIME data
