How to add another route in a form module

I’ve created a Form in module. It is working fine but unable to add another route. I’ve created another yml file and it’s corresponding code in src/Form/xyz.php but it’s giving this error. The existing working route yml file is:

license_check.change_license:   path: '/change_license'   defaults:     _form: 'Drupal\license_check\Form\ChangeLicense'     _title: 'Change License'   requirements:     _permission: 'access content'
