Hi!

The output shows that psr/cache 3.0 is installed, which does come with the correct signature: https://github.com/php-fig/cache/blob/3.0.0/src/CacheItemInterface.php#L89

So there must be something wrong with your environment. Did you by any chance installed the php-psr extension? This extension is not officially supported and is known to cause these type of type mismatches (ref). PSR packages only officially support installation through Composer.

moving to discussions, as this is not a bug within Symfony as far as I can see
