Coverage error in Search Console after modification of htaccess

Question

In the last year, my website has had a problem with many 404 errors where .html was added to URLs that shouldn't have it. To resolve this problem I modified the HTACCESS with this line:

RewriteEngine On
RewriteRule ^(.*)\.html$ /$1 [L,R=301]

#301 from example.com/page.html to example.com/page
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /.*\.html\ HTTP/
RewriteRule ^(.*)\.html$ /$1 [R=301,L]

but after this addition, I've see more errors in search console. Many of them are redirect errors with this type of URL:

.../tag/windows-10/page/2/?amp%25252525252525252525252525252525252525252525252525252525252525252525252525252Fpage%25252525252525252525252525252525252525252525252525252525252525252525252525252F6%2525252525252525252525252525252525252525252525252525252525252525252525252Famp%2525252525252525252525252525252525252525252525252525252525252525252525252F%25252525252525252525252525252525252525252525252525252525252525252525252Famp%25252525252525252525252525252525252525252525252525252525252525252525252F%252525252525252525252525252525252525252525252525252525252525252Famp%252525252525252525252525252525252525252525252525252525252525252F%2525252525252525252525252525252525252525252525252525252525252Famp%2525252525252525252525252525252525252525252525252525252525252F%25252525252525252525252525252525252525252525252525252Famp%25252525252525252525252525252525252525252525252525252F%252525252525252525252525252525252525252525252525252Famp%252525252525252525252525252525252525252525252525252F%2525252525252525252525252525252525252525252525252Famp%2525252525252525252525252525252525252525252525252F%25252525252525252525252525252525252525252525252Famp%25252525252525252525252525252525252525252525252F%25252525252525252525252525252525252525252Famp%25252525252525252525252525252525252525252F%25252525252525252525252525252525252Famp%25252525252525252525252525252525252F%252525252525252525252525252525252Famp%252525252525252525252525252525252F%2525252525252525252525252Famp%2525252525252525252525252F%2525252525252525252Famp%2525252525252525252F%25252525252525252Famp%25252525252525252F%25252525252Famp%25252525252F%252525252Famp%252525252F%2Famp%2F/amp//amp/

What's wrong? What can I modify to avoid a redirect of the amp pages?
