Elastic Beanstalk Configuration update

It's possible that there may be a compatibility issue between your Elastic Beanstalk environment and the new configuration panel.

You may want to try updating the Elastic Beanstalk CLI to the latest version and then try updating your environment configuration through the CLI. This will allow you to see any error messages that may be preventing your configuration changes from being applied.

Alternatively, you can try creating a new Elastic Beanstalk environment with the desired configuration settings and deploy your application to the new environment. This will allow you to start fresh with the new configuration panel.

If neither of these options work, you may want to contact AWS Support for further assistance in troubleshooting the issue.
