Describe the bug
The WooCommerce Stripe plugin causes a critical error when accessing and editing the checkout page in the WordPress backend. The issue occurs specifically when using the Classic Checkout block, whereas using the [woocommerce_checkout] shortcode works without issues.

To Reproduce
Steps to reproduce the behavior:

1. Install and activate the WooCommerce Stripe plugin.
2. Go to WooCommerce > Settings > Payments and enable Stripe.
3. Ensure the Checkout page is using the Classic Checkout block, not the [woocommerce_checkout] shortcode
4. Attempt to edit the Checkout page in the WordPress backend. Pages > Checkout > Edit Page
5. A critical error appears, preventing page access.

Expected behavior
The checkout page should be editable in the backend without errors.

Screenshots
The block that causes the critical error:

Error while trying to edit the checkout page when the stripe payment options are active:

Adding [woocommerce_checkout] in a shortcode block does not cause any issue

Environment (please complete the following information):

• WordPress Version 6.7.1
• WooCommerce Version 9.6.1
• Stripe Plugin Version 9.1.1
• WooCommerce and Stripe Plugin only.

Additional context
Switching to the [woocommerce_checkout] shortcode bypasses the problem.
