TYPO3 Core

As of today, searching for core updates in Installations Tool returns the following error

DateTimeImmutable::__construct() expects parameter 1 to be string, null given

in /typo3_src-10.4.30/typo3/sysext/install/Classes/CoreVersion/CoreRelease.php line 46

    public static function fromApiResponse(array $response): self
    {
        return new self($response['version'], new \DateTimeImmutable($response['date']), $response['type'], $response['tar_package']['sha1sum'], $response['elts'] ?? false);
    }

The error probably affects several TYPO3 installations, so I can rule out that it is only due to one system
