Issue publishing the config file

[Former user]

I was following the steps for installation, but when I try to publish the config file like:

php artisan useradmin:config

I got {"error":{ "type":"Symfony\\Component\\Debug\\Exception\\FatalErrorException","message": "Can't use method return value in write context", "file":"C:\\Users\\esteban\\Desktop\\hostels\\vendor\\hampel\\useradmin\\src\\Hampel\\Admin\\Users\\Console\\UserFindCommand.php","line":45}}

I also tried `php artisan useradmin:publish config'. Any idea how to fix this? I'm using Windows.
