Opening Links from my Home Page doesn’t work after migrating to another Webhost

Hi,

After migrating my wordpress site ranayoga.com the links on my home page are not working anymore.

For example the link:
https://ranayoga.com/kontakt/

It should lead to my contact page, but I get the error:
https://ibb.co/RNs5mV9

What I did:
I exported my wordpress site with the Plugin Duplicator from my old webhoster.

I then set the document root of my domain ranayoga.com in the Customer Control Panel of my webhoster to:
httpdocs/ranayoga.com/www

I then installed a new wordpress website on the installation path:
https://ranayoga.com/

After installation I can find the website in the file manager here:
httpdocs/ranayoga.com/www

I uploaded the exported files from Duplicator into the folder of the website and installed it.

My home page ranayoga.com works like it should, but as I said I can’t open the links to my other pages like https://ranayoga.com/kontakt/ because I get server error 500.

In my log files there is the following written about server error 500:
https://ibb.co/3Cv1c0W

In the .htaccess file which is located in the wordpress installation folder there is written the following:

#This Apache config file was created by Duplicator Installer on 2021-09-13 12:01:49.
#The original can be found in archived file with the name .htaccess__[HASH]

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

In the WordPress Dashboard under Settings / General the WordPress Address (URL) and the Site Address (URL) are both:
https://ranayoga.com/

Do you know what I have to do to reach i.e. my contact page via this URL again?
https://ranayoga.com/kontakt
