commerce cart page says access denied after enabling this module

Please let me know both the versions of Drupal and of Commerce?

Drupal Version is 10.2.1
Commerce braintree version is 8.x-1.5
Php version 8.1.0

And I have followed configuration scenarios as mentioned in module, but I can see below js error as shown in attached screenshot
on this page(/admin/commerce/config/donation-settings) when i try to save the page .

Can you please help to fix this and also allow user to access cart route by using this module.

I cannot reproduce your reported JS error, but I am re-validating the setup for standard cart checkout.

Either you have not properly configured the module in your local instance, or there is a conflict with something else you have installed. I have verified that this module works with the Drupal 10.1 and the latest version of Commerce when it is properly configured. I have provided detailed documentation (screenshot attached for anyone else browsing issues).

Based on your screenshot I think you missed creating and configuring a replacement checkout flow using the provided multi-step with donation flow. Checkout on the /cart route is blocked by design when the module is not properly configured because it does not properly process orders. The default settings for this module are for a scenario in which donations are the only commerce on the site.

I see that you have been part of our community for 15 years, so I'm surprised that you also used my drupal.org contact form to communicate that I was not responding to your bug report. We share these contributed modules in the same way that one brings a dish to a communal feast. It's not our culture to treat the issue queue as a customer service channel but as a shared kitchen in which we all cook.

Thank you for the reply.I have followed all the instructions mentioned in https://www.drupal.org/files/issues/2024-03-11/commerce_donation_instruc... →

I have created a checkout flow that uses this modules's donation_multistep_flow plugin.
and also placed "Add Donation" pane in the first step of the flow, just before the Donation step.
Choose the /cart route option below with
The Donation OrderItem type.
The Default Order type.
and choosen donation checkout flow with donation_multistep_flow

I am also attaching screenshots below for your reference which includes my checkout flow with donation_multistep_flow.

The same at my site
uninstalling the module fixed this issue.
