HTACCESS 301 redirect to solve redirect error in google search console?

Question

Do you have any idea why google search console gives a redirection error? I've been trying to solve this problem for days. My website: https://www.energiatanusitvany-budapesten.hu/ I've set up every essential redirection (non-www. to www., with "/" to without "/", with ".html" to without ".html", http:// to https://) Something is wrong with the .html trimming. Search console gives these indexing and redirectional errors: Referral links:https://www.energiatanusitvany-budapesten.hu/energetikai-tanusitvanyhttps://www.energiatanusitvany-budapesten.hu/energetikai-tanusitvany.html

Referral links: http://www.energiatanusitvany-budapesten.hu/adatvedelem.htmlhttps://www.energiatanusitvany-budapesten.hu/adatvedelem

This is how my .htaccess file looks like:

RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.energiatanusitvany-budapesten.hu/$1 [R=301,L]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /$1 [NE,R=301,L]

RewriteCond %{THE_REQUEST} /([^.]+)\.html [NC]
RewriteRule ^ /%1 [NC,L,R]

RewriteCond %{REQUEST_FILENAME}.html -f
RewriteRule ^ %{REQUEST_URI}.html [NC,L]

RewriteOptions inherit
