Apache no longer starts after editing vhosts file

[Omoioma]

This is more of a XAMPP issue but I will still post here.

I tried to edit the httpd-vhosts.conf and add the following code:
##<VirtualHost 127.0.0.1:443>
##ServerName www.youtube.com
##DocumentRoot "C:/xampp/htdocs"
##SSLEngine on
##SSLCertificateFile "conf/ssl.crt/server.crt"
##SSLCertificateKeyFile "conf/ssl.key/server.key"
##<Directory "C:/xampp/htdocs">
AllowOverride All
Require all granted
##
##

But XAMPP gives me this error.

8:39:09 AM [Apache] Error: Apache shutdown unexpectedly.
8:39:09 AM [Apache] This may be due to a blocked port, missing dependencies,
8:39:09 AM [Apache] improper privileges, a crash, or a shutdown by another method.
8:39:09 AM [Apache] Press the Logs button to view error logs and check
8:39:09 AM [Apache] the Windows Event Viewer for more clues
8:39:09 AM [Apache] If you need more help, copy and post this

Changing the ports do not help.

That XML is severely malformed.

Try adding this instead:

<VirtualHost 127.0.0.1:443>
   ServerName www.youtube.com
   DocumentRoot "C:/xampp/htdocs"
   SSLEngine on
   SSLCertificateFile "conf/ssl.crt/server.crt"
   SSLCertificateKeyFile "conf/ssl.key/server.key"
   <Directory "C:/xampp/htdocs">
      AllowOverride All
      Require all granted
   </Directory>
</VirtualHost>
