In these lines :

RewriteCond %{HTTPS} off RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

You have enforced all http requests into https as they are , whether come with or without www ,

So , change these lines with this :

RewriteCond %{HTTPS} off  [OR]
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^  https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
