CSS is not connected on the site, what is the reason?

Question

htaccess

Stopped connecting css on the site. Before that everything was working fine. It is interesting that the admin panel authorization page is displayed normally.
It all looks like this:
In .htaccess it is:

RewriteEngine On

#Redirect with www-web-site on without www
Options +FollowSymLinks
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.domain\.com$ [NC]
RewriteRule ^(.*)$ http://domain.com/$1 [R=301,L]

#Redirect on https
RewriteEngine On
RewriteCond %{HTTPS} =off 
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [QSA,L]

#Protecting your site from script injection

#Includes sim link tracking

#Start url_rewriting
RewriteEngine On

#Block all links contains <script>
RewriteCond %{QUERY_STRING} (\<|%3C).*script.*(\>|%3E) [NC,OR]

#Blocks all scripts that try to change variables PHP Globals:
RewriteCond %{QUERY_STRING} GLOBALS(=|\[|\%[0-9A-Z]{0,2}) [OR]

#Blocks all scripts that try to change variable _REQUEST:

#Redirect on home page
RewriteRule ^gofolder/(.*)$ https://domain.com/$1 [R=301,L,NC]
