I’m upgrading my 5.2.1 installation to 6.0.0 with the composer method documented here: [How to update Mautic — Mautic Documentation 0.1 documentation](https://docs.mautic.org/en/5.x/getting_started/how_to_update_mautic.html#updating-mautic-composer-based-installs) . php version is 8.1.31.

After running `php bin/console cache:clear` about any bin/console command fails with this message:

> In PhpDumper.php line 1969:  
> Argument 2 of service “twig.command.lint” is abstract: File name pattern

I still have this issue. Trying to upgrade from 5.2.5 to 6.0.1:

```auto
php bin/console cache:clear --no-warmup

In PhpDumper.php line 1969:
                                                                             
  Argument 2 of service "twig.command.lint" is abstract: File name pattern.  
                                                                             

```

Deleting everything and restoring config/local.php did work around my issue.
