Problem/Motivation
After upgrading from Redirect 1.10 to 1.11, I got "The website encountered an unexpected error. Please try again later." error. In the error log I see this:
ParseError: syntax error, unexpected 'protected' (T_PROTECTED), expecting variable (T_VARIABLE) in /app/web/modules/contrib/redirect/src/EventSubscriber/RouteNormalizerRequestSubscriber.php on line 71 #0 /app/vendor/composer/ClassLoader.php(427): Composer\Autoload\{closure}('/app/web/module...')

ParseError: syntax error, unexpected 'protected' (T_PROTECTED), expecting variable (T_VARIABLE) in Composer\Autoload\{closure}() (line 71 of /app/web/modules/contrib/redirect/src/EventSubscriber/RouteNormalizerRequestSubscriber.php).
[warning] Drush command terminated abnormally.
Steps to reproduce
Upgrade Redirect from 1.10 to 1.11 if you use Drupal 9.5.11 and php 7.4.33 (I know, outdated, but the module still indicates that I can use it: `core_version_requirement: ^9.2 || ^10 || ^11`).
Proposed resolution
I don't exactly know, but I see that there were changes regarding the above error in the last version: https://git.drupalcode.org/project/redirect/-/compare/8.x-1.10...8.x-1.1...
