ACSC Windows Hardening Guidelines causes Microsoft Edge to stop loading web pages after approximately 10 minutes.

Hi Team
During our testing we have found that applying the "ACSC Windows Hardening Guidelines" policy set to devices would result in Microsoft Edge breaking.

After approximately 10 minutes, edge will fail to load new tabs or web pages resulting in the tabs no longer responding at all.
Microsoft edge task needs to be ended before Edge will load tabs and pages again.

This seems to be triggered by opening a new tab after about 10 mins.

We have been testing the policy set and have confirmed that it seems to be a policy(s) under "Administrative Templates" that are causing it.
We removed the "Administrative Templates" Category from the policy set and sync the test devices and confirmed the issue seems to stop.
It's been very painful trying to disable one policy at a time. Wondering if i can get any support with this.

Thanks!
