My edge case is that I have Gin as the frontend theme and Claro as the backend theme. Yes, I know this is crazy, and I've only switched to Claro temporarily to test something, ensuring that a render issue in views is not caused by Gin.
But this crazy scenario exposed a tiny issue that can easily be resolved. In gin_page_attachments_alter we call this:
'#value' => new FormattableMarkup('{ "ginDarkmode": "@value" }', ['@value' => $settings->get('enable_darkmode')]),
In the scenario above, the setting returns NULL which will later be passed on to \Drupal\Component\Utility\Html::escape and that throws an exception because the given text has to be string and can't be NULL.
Provide a default value in this case.

Hello Jurgen,
Indeed the patch resolves the issue.
Thanks for the great work.
Adding related issue from gin toolbar not sure if they should solve the same way.
I had this issue on a fresh D11 install after enabling Gin and the patch fixes it.
