You don’t have access to this module.

When an editor (a backend user that is not an administrator) tries to access a module to where they have no access to an exception like this will be thrown:

Core: Exception handler (WEB):
Uncaught TYPO3 Exception: #1294586448: Access Error: You don't have access to this module.
RuntimeException thrown in file /var/www/html/vendor/typo3/cms/typo3/sysext/core/Classes/Authentication/BackendUserAuthentication.php in line 448.

In the media extension this happens for example if the access to the modules is not configured properly.

Check the following access: A backend user with access to File>Media must also granted to User tools > Media Extra (hidden module, required for non admin).
