Can't load admin panel in 4.12.4 on the public internet

Bug report

Required System information

• Node.js version: v18.17.0
• NPM version: 9.6.7
• Strapi version: 4.12.4
• Database: aurora postgres 14.6
• Operating system: the docker container node:18-alpine, Linux 30339f198cc4 5.15.49-linuxkit-pr #1 SMP PREEMPT Thu May 25 07:27:39 UTC 2023 aarch64 Linux

Describe the bug

The Strapi admin panel won't load. It shows an error banner with the text:

Warning: An error occurred while requesting the API

Looking in the browser console, the browser also tries to make several requests to http://localhost:1337, which makes no sense on the public internet. I haven't changed any configurations between 4.12.1 and 4.12.4.

Steps to reproduce the behavior

1. Visit a strapi admin panel deployed to an environment other than localhost

Expected behavior

The admin panel loads.

Additional context

I tried setting STRAPI_ADMIN_BACKEND_URL manually to the domain where my strapi server is, but it didn't work.

Just want to confirm, I also have the same error after upgrade to 4.12.4 today, need to downgrade for now

We've encountered the same issue by not upgrading strapi to v4.12.4 (it stays at v4.12.1), but rather upgrading @strapi/design-system to v1.9.0. Downgrading @strapi/design-system to v1.8.2 fixed the problem.

(We've also upgraded @strapi/icons to v1.9.0 and also downgraded it to v1.8.2, but I guess this shouldn't matter as it only provides icons...)

Can also confirm, after upgrading to 4.12.4 from 4.12.1.

-        "@strapi/plugin-graphql": "^4.12.1",
-        "@strapi/plugin-i18n": "4.12.1",
-        "@strapi/plugin-users-permissions": "4.12.1",
-        "@strapi/strapi": "4.12.1",
+        "@strapi/plugin-graphql": "^4.12.4",
+        "@strapi/plugin-i18n": "4.12.4",
+        "@strapi/plugin-users-permissions": "4.12.4",
+        "@strapi/strapi": "4.12.4",

I've just tried to create a new strapi-app with npx create-strapi-app@latest and did not run into this issue, i'll check the upgrade path now but can I confirm when you updated your strapi app you re-ran the build command to ensure the admin panel is rebuilt? :)

Edit: i've just created an app at 4.12.1 and then upgraded to 4.12.4 and still do not receive this error, can you please provide a reproduction?
