Endlosschleife beim Anmelden im Backend

Hallo, 

da ich es nicht hinbekommen habe Shopware 6 zu installieren habe ich jetzt Shopware 5 installiert, das Frontend funktioniert super, aber wenn ich ins Backend gehe, startet sich der First Run Wizard, da kam gleich Mal eine Fehlermeldung, ich ignorierte diese und machte weiter. Als ich alles eingestellt hatte, startete der First Run Wizard erneut und das wiederholt sich jetzt jedes Mal.

Hier ist die Fehlermeldung: 

Ups! Ein Fehler ist aufgetreten! Die nachfolgenden Hinweise sollten Ihnen weiterhelfen. An exception occurred while executing 'INSERT INTO s_core_config_values (element_id, shop_id, value) VALUES ( (SELECT id FROM s_core_config_elements WHERE name LIKE 'trackingUniqueId' LIMIT 1), 1, ? )' with params ["s:32:\"WzNoB4G3hCA68kqsQ5YrK9fOsTffUPym\";"]: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '966-1' for key 'element_id_shop_id' in vendor/doctrine/dbal/lib/Doctrine/DBAL/DBALException.php on line 179 Stack trace: #0 vendor/doctrine/dbal/lib/Doctrine/DBAL/DBALException.php(150): Doctrine\DBAL\DBALException::wrapException(Object(Doctrine\DBAL\Driver\PDOMySql\Driver), Object(PDOException), 'An exception oc...') #1 vendor/doctrine/dbal/lib/Doctrine/DBAL/Connection.php(1065): Doctrine\DBAL\DBALException::driverExceptionDuringQuery(Object(Doctrine\DBAL\Driver\PDOMySql\Driver), Object(PDOException), 'INSERT INTO s_c...', Array) #2 engine/Shopware/Bundle/PluginInstallerBundle/Service/UniqueIdGenerator/UniqueIdGenerator.php(96): Doctrine\DBAL\Connection->executeUpdate('INSERT INTO s_c...', Array) #3 engine/Shopware/Bundle/PluginInstallerBundle/Service/UniqueIdGenerator/UniqueIdGenerator.php(57): Shopware\Bundle\PluginInstallerBundle\Service\UniqueIdGenerator\UniqueIdGenerator->storeUniqueIdInDb(' *********...') #4 engine/Shopware/Bundle/PluginInstallerBundle/StoreClient.php(285): Shopware\Bundle\PluginInstallerBundle\Service\UniqueIdGenerator\UniqueIdGenerator->getUniqueId() #5 engine/Shopware/Controllers/Backend/FirstRunWizardPluginManager.php(217): Shopware\Bundle\PluginInstallerBundle\StoreClient->doTrackEvent('First Run Wizar...') #6 engine/Library/Enlight/Controller/Action.php(192): Shopware_Controllers_Backend_FirstRunWizardPluginManager->getAvailableLocalizationsAction() #7 engine/Library/Enlight/Controller/Dispatcher/Default.php(478): Enlight_Controller_Action->dispatch('getAvailableLoc...') #8 engine/Library/Enlight/Controller/Front.php(228): Enlight_Controller_Dispatcher_Default->dispatch(Object(Enlight_Controller_Request_RequestHttp), Object(Enlight_Controller_Response_ResponseHttp)) #9 engine/Shopware/Kernel.php(184): Enlight_Controller_Front->dispatch() #10 vendor/symfony/http-kernel/HttpCache/SubRequestHandler.php(102): Shopware\Kernel->handle(Object(Symfony\Component\HttpFoundation\Request), 1, true) #11 vendor/symfony/http-kernel/HttpCache/HttpCache.php(448): Symfony\Component\HttpKernel\HttpCache\SubRequestHandler::handle(Object(Shopware\Kernel), Object(Symfony\Component\HttpFoundation\Request), 1, true) #12 engine/Shopware/Components/HttpCache/AppCache.php(256): Symfony\Component\HttpKernel\HttpCache\HttpCache->forward(Object(Symfony\Component\HttpFoundation\Request), true, NULL) #13 vendor/symfony/http-kernel/HttpCache/HttpCache.php(238): Shopware\Components\HttpCache\AppCache->forward(Object(Symfony\Component\HttpFoundation\Request), true) #14 engine/Shopware/Components/HttpCache/AppCache.php(99): Symfony\Component\HttpKernel\HttpCache\HttpCache->pass(Object(Symfony\Component\HttpFoundation\Request), true) #15 shopware.php(122): Shopware\Components\HttpCache\AppCache->handle(Object(Symfony\Component\HttpFoundation\Request)) #16 {main}
