Infinite Redirect Loop on Activation

I have an issue with this plugin triggering an infinite redirect loop on certain site/server combinations. It’s clearly triggered by the following:

/**
 * On activate redirect to settings page
 */
register_activation_hook(__FILE__, function () {
	add_option('cfturnstile_do_activation_redirect', true);
	add_option('cfturnstile_tested', 'no');
});
add_action('admin_init', function () {
	if (get_option('cfturnstile_do_activation_redirect', false)) {
		delete_option('cfturnstile_do_activation_redirect');
			exit(wp_redirect("/wp-admin/options-general.php?page=simple-cloudflare-turnstile%2Finc%2Fadmin-options.php"));
	}
});

My questions:

• Is there something obvious I’m missing to avoid this?
• Is there a way to create an override of the cfturnstile_do_activation_redirect option?
• Could this hook be refactored to at least include a named function instead of an anonymous function, so I could manually de-register it?

Thanks
