How to make a 301 redirect of the /en/ directory to the main page using .htaccess?

Question

htaccess

You need to redirect https://site.com/en/ to https://site.com/ and all internal pages.
there is a qtranslate x plugin and there is a 302 redirect through it, and this is wrong.
Simply put, how to remove the /en/ level?
Can you please tell me what to write in htaccess?
