Tryed in 9.5.11

if ($this->useNavTitle && trim($page['nav_title'] ?? '') !== '') {

CHANGE TO

$navTitleTrim = isset($page['nav_title']) ? $page['nav_title'] : '';
     if (is_null($navTitleTrim)) {
         $navTitleTrim = '';
     }
        if ($this->useNavTitle && trim($navTitleTrim) !== '') {
            $nameSourceField = 'nav_title';
            $visibleText = $page['nav_title'];
        }
     if (is_null($visibleText)) {
         $visibleText = '';
     }

was working. In TYPO3 v10 not working anymore.

Status changed from New to Needs Feedback

Can you please check whether the request really uses PHP 7.2 or newer? Since a syntax error is reported, I assume some PHP version is used that is not capable of the null coalesce operator (which came in with PHP 7.0!). Your proposed workaround is suitable for PHP < 7.0.

PHP Version changed from 7.2 to 7.3

I was taking a look in the backend. It is "PHP Version 7.3.10".

I really wonder what's wrong here. Can you check if PHP 7.3 is also used for that very request that fails? I assume a pretty broked server setup here.

Was calling phpinfo() inside TreeController.php with

ob_start();
    phpinfo();
    $info = ob_get_contents();
    ob_end_clean();

    $fp = fopen("222.txt", "w+");
    fwrite($fp, $info);
    fclose($fp);
