 * Could you deactivate all plugins and activate a default theme? If the problem
   then no longer occurs, it must have to do with one of them. Possibly it was caused
   by an incompatibility of the plugin/theme with WordPress 6.0, which was released
   yesterday evening.

 * There is an issue with WordPress 6 that makes the website inaccessible with a
   fatal error, especially in script-loader.php file on line 1271. If you search
   on Google for “script-loader.php on line 1271” you will find many websites that
   are affected by this error.
    There is a temporary fix that we can use, but the
   real and permanent fix should come from WordPress team as an update. The fix 
   is: Open /wp-includes/script-loader.php file and removed the second % from the
   line 1266: `__( 'Hurray! Your theme supports Full Site Editing with blocks. <
   a href="%1$s">Tell me more</a>. %2$s' ),` It should look like this: `__( 'Hurray!
   Your theme supports Full Site Editing with blocks. <a href="%1$s">Tell me more
   </a>. 2$s' ),` The fix is posted here: [https://stackoverflow.com/a/72413198](https://stackoverflow.com/a/72413198)

 * This looks like a different error than mentioned in this topic. In addition, 
   manipulating core files is not advisable. Why haven’t you created a ticket in
   Trac yet? Maybe it is also due to the language files used, because there is already
   a ticket there: [https://core.trac.wordpress.org/ticket/55866](https://core.trac.wordpress.org/ticket/55866)

 * Yes, you are right, but maybe the error is related to the same issue as it is
   coming from the same core file.
    I know that manipulating the core files is no
   advisable, but that was the only fix, or we should downgrade WordPress to fix
   it. Yes, there is already a ticket about that issue, and it seems that it is 
   coming from the language file, but I don’t know if it was fixed or not yet.
