Problem/Motivation
Accessing the OG role permissions form results in a fatal error when the OG role object is not available.
The website encountered an unexpected error. Try again later.
Error: Call to a member function getLabel() on null in Drupal\og_ui\Form\OgRolePermissionsForm->rolePermissionTitleCallback() (line 44 of /var/www/html/og_ui/src/Form/OgRolePermissionsForm.php).

Steps to reproduce
- Install and enable the
og and og_ui modules.
- Create a group content type and add an OG group.
- Visit the OG role permissions page (e.g.,
/admin/config/group/permissions/node/committee/does-not-exist) for a non-existent or invalid role ID.
- Observe the error:
Call to a member function getLabel() on null.
Proposed resolution
Maybe copy what core does... we'll see
User interface changes
None expected. The fix will prevent a fatal error and ensure the intended permissions UI loads or fails gracefully.
