Your error is not visible.
Anyway, the 2 last arguments of generate_yes_no_radio must be arrays or nothing, not strings:

$form_container->output_row($lang->couponcodes_used_only, $lang->couponcodes_used_only_desc, $form->generate_yes_no_radio('usedonly', 0, true, [], []), 'usedonly');

or:

$form_container->output_row($lang->couponcodes_used_only, $lang->couponcodes_used_only_desc, $form->generate_yes_no_radio('usedonly', 0, true), 'usedonly');
