Update from 5 to 6 is done through the composer but the home page keep directing to the installer page

Your software
My Mautic version is: 6.0.7
My PHP version is: 8.3.20
My Database type and version is: MySQL 8

Your problem
My problem is: Update from 5 to 6 is done through the composer, but the home page keep directing to the installer page(Install | Mautic)

These errors are showing in the log: no error except this one

hassan@mautic-deploy-prod-instance:/var/www/mautic$ sudo -u www-data php /var/www/mautic/bin/console doctrine:schema:validate

PHP Warning:  Module "mbstring" is already loaded in Unknown on line 0

Mapping

-------

 [FAIL] The entity-class Mautic\DynamicContentBundle\Entity\DynamicContentLeadData mapping is invalid:

 * The association Mautic\DynamicContentBundle\Entity\DynamicContentLeadData#dynamicContent refers to the inverse side field Mautic\DynamicContentBundle\Entity\DynamicContent#id which is not defined as association.

 * The association Mautic\DynamicContentBundle\Entity\DynamicContentLeadData#dynamicContent refers to the inverse side field Mautic\DynamicContentBundle\Entity\DynamicContent#id which does not exist.

Database
--------                                                                                                                  
 [ERROR] The database schema is not in sync with the current mapping file. 

Steps I have tried to fix the problem:
