Steps to reproduce
Go to Structure > Content Types > "content_type" > Manage Display then the page crashes in the error above.
Proposed resolution
On line 1006 of ds.module file, inside the ds_field_formatter_settings_summary_alter() change $parameters = \Drupal::routeMatch()->getRawParameters(); to $parameters = \Drupal::routeMatch()->getParameters();
Remaining tasks
User interface changes
API changes
Data model changes
