Can't connect to admin

[FrankJL]

I did a transfer from the working site to my local computer (MacOS) with MAMP Pro. This site is working, but I can't enter the admin mode.

The admin is working fine on the production site.

I always get: HTTP ERROR 500 and in hte PHP log I see:

[16-Oct-2024 20:21:03 Europe/Brussels] PHP Fatal error:  Uncaught Symfony\Component\Yaml\Exception\ParseException: The constant "PrestaShopBundle\Service\Form\MultistoreCheckboxEnabler::MULTISTORE_FIELD_PREFIX" is not defined at line 71 (near "multistore_field_prefix: !php/const PrestaShopBundle\Service\Form\MultistoreCheckboxEnabler::MULTISTORE_FIELD_PREFIX"). in /Users/frank/Sites/prestafrank/vendor/symfony/symfony/src/Symfony/Component/Yaml/Inline.php:720
