I also got this error. I have built a website on my Raspberry Pi to learn and have fixed many errors for this.
To solve this error:
Step 1: enable rewrite module

$ sudo a2enmod rewrite
$ systemctl restart apache2

Step 2: modify apache site configuration
$ sudo nano /etc/apache2/sites-available/000-default.conf

add some directives like below:

<VirtualHost *:80>
    ServerName example.com
    ServerAlias www.example.com
    
    RewriteEngine on
    RewriteCond %{SERVER_NAME} =example.com [OR]
    RewriteCond %{SERVER_NAME} =www.example.com
    RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
    
    <directory /var/www/html>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Require all granted
    </directory>

    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Restart Apache
$ systemctl restart apache2

I read from this post Removing Index.php From the URL Slug in WordPress

Changing permalink and setting .htaccess doesn’t not work with me. The .htaccess file is overwritten each time changing permalink and presssing Save button.

I can only create and post new page if I add index.php in the link

Example: in Settings > Permalinks > Custom Structure
https://mysite.com/index.php/%postname%/
https://mysite.com/index.php/archives/%post_id%
https://mysite.com/index.php/%year%/%monthnum%/%postname%/
