Route "entity.backup_migrate_settings.canonical" error

I am getting the following also with 5.0.3 and D10.2.5 and PHP 8.2.17:

Symfony\Component\Routing\Exception\RouteNotFoundException: Route "entity.backup_migrate_settings.canonical" does not exist. in Drupal\Core\Routing\RouteProvider->getRouteByName() (line 206 of core\lib\Drupal\Core\Routing\RouteProvider.php).

I tried to reproduced it with 5.0.3 and D10.2.5 and PHP 8.2, and it is working as expected.

I also searched entity.backup_migrate_settings.canonical in the code base of Backup and Migrate module, but it is not exists in anywhere.

Can you guys please reconfirm your versions?

Thanks
Samit K.

should have also mentioned using Version: 5.0.3 of backup_migrate

Added an empty route. This fixed the issue. Changes are in the fork.
