Bug Description
When opening the Strapi admin dashboard (v5.28.0), the Content-Type Builder, Content Manager, and Media Library fail to load. The following errors appear in the console:

TypeError: checkUserHasPermissions is not a function
TypeError: Cannot read properties of undefined (reading 'tours')

Creating a new super admin user or resetting credentials does not resolve the issue. API tokens and permissions are not visible in the admin panel, and entries cannot be added through the dashboard.

Steps Taken / Commands Tried:
I have already tried the following steps to fix the issue:
rm -rf node_modules
rm -rf build
rm -rf .cache
rm -rf dist
npm install
npm run build
npm run develop

Despite these attempts, the admin dashboard still fails to load correctly.
