Connect-AzAccount is hanging

### Description

**Connect-AzAccount is hanging**
On issuing Connect-AzAccount, post verification of login, it stays hanging without any progress

I found out that with the latest version of The Az.Accounts, 2.8.0, running the following command:

**PS C:\Users\Administrator.AZS-DVM> Connect-AzAccount -Environment "AzureStackAdmin" -Debug -Verbose**
DEBUG: 9:23:53 AM - ConnectAzureRmAccountCommand begin processing with ParameterSet 'UserWithSubscriptionId'.

Confirm
Continue with this operation?

The same behavior is observed with Az 8.0.0 version module.

### Error output

_No response_

Start by reproducing Connect-AzAccount -Environment "AzureStackAdmin" -Debug -Verbose with Az.Accounts 2.8.0 or Az 8.0.0 on the reported Windows PowerShell environment. Trace the authentication flow after login verification, where the debug output stops, and use the reported module and environment details to identify the hang. Done means the command completes or reports a clear failure instead of remaining unresponsive.
