Shield Module Stops Working After Adding and Removing Excluded Path for JSONAPI

Problem/Motivation

I am using the Shield module along with the REST API Authentication → module to manage access to JSON:API endpoints. The issue arises when adding and removing paths from the Shield configuration:

• Adding /jsonapi/* to the "Exclude paths" section allows JSON:API requests as expected.
• However, after removing /jsonapi/* from the configuration, Shield stops blocking access to the entire site.

This behavior prevents Shield from functioning as intended, even after revert the chnages. It works only after I uninstall and reinstall again and re-configure

Steps to reproduce

1. Install and enable the Shield module.
2. Add /jsonapi/* to the "Exclude paths" configuration.
3. Test access to a JSON:API endpoint using Postman. Confirm it works without Shield blocking it.
4. Remove /jsonapi/* from the Shield "Exclude paths" configuration.
5. Test access to various URLs, and notice that Shield no longer protects any URLs.
