We are managing a lot of WordPress websites under our Server Management plan and we will be doing regular updates by our expert engineers to prevent all vulnerabilities.

1. Tweaking PHP Version
If your PHP version is older (5.6) then you can update it to PHP 7.4 OR latest in order to solve.

2. Update the .htaccess file

This error can happen when updating WordPress to the latest version because of incorrect mod_rewrite rules. Check the .htaccess file that if it is configured properly with the below default code.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

We can create a new .htaccess file by goes to the wp-admin link and Settings –> Permalink, without changing anything we can save it. Then WordPress will automatically create a .htaccess for it.
