Thanks @bniranjanbhat for reporting!

We've identified the root cause of this issue, which was we relied on $Host.Version as the version of PowerShell, and used it to determine which assemblies to load. But in some cases (for example a remote PS session) it's not essentially the version we want. We should have used $PSVersionTable instead.

For now the work-around is to uninstall Az.Accounts v2.11.0 and install v2.10.4 instead.

Uninstall-Module Az.Accounts -RequiredVersion 2.11.0 -Force
Install-Module Az.Accounts -RequiredVersion 2.10.4

# Alternatively, install both versions side by side and import v2.10.4 explicitly
Install-Module Az.Accounts -RequiredVersion 2.10.4 -Force
Import-Module Az.Accounts -RequiredVersion 2.10.4

In the meantime, we plan to release a hotfix of Az.Accounts soon. We will keep the thread updated.

Az module 9.1.1. is including version Az.Accounts 2.10.4, in this case downgrade to 9.1.1. would solve two issues until newer version is released for Az.

When importing newest version i got:
Import-Module : Der Typ "System.Globalization.CultureInfo" in der Assembly "System.Runtime, Version=4.0.0.0, Culture=neutral,

How do i downgrade to 9.1.1 with the Az.Accounts 2.10.4 version?
