Loading dependent assemblies load incorrect versions, resulting in "Method not found" exception

Description

Powershell 7.5.5
Az 15.4.0

The Connect-AzAccount command fails due to the following:

Connect-AzAccount
Please select the account you want to login with.

WARNING: Unable to acquire token for tenant 'organizations' with error 'Method not found: 'System.Threading.Tasks.Task1<Azure.Identity.AuthenticationRecord> Azure.Identity.InteractiveBrowserCredential.AuthenticateAsync(Azure.Core.TokenRequestContext, System.Threading.CancellationToken)'.' Connect-AzAccount: Method not found: 'System.Threading.Tasks.Task1<Azure.Identity.AuthenticationRecord> Azure.Identity.InteractiveBrowserCredential.AuthenticateAsync(Azure.Core.TokenRequestContext, System.Threading.CancellationToken)'.

The assemblies from Az Modules folder are not loaded, while assemblies from GAC loads:

[System.AppDomain]::CurrentDomain.GetAssemblies() | Where-Object { $_.Location -like "GAC" }

GAC Version Location

False v4.0.30319 C:\WINDOWS\Microsoft.NET\assembly\GAC_MSIL\Azure.Identity\v4.0_1.14.2.0__92742159e12e44c8\Azure.Identity.dll

This was tested with pwsh -NoProfile

Can the issue becaused by the logic in tools/Tools.Common/Loaders/AssemblyLoader.cs ?

Here are some similar issues that might help you. Please check if they can solve your problem.

• Connect-AzAccount works through powershell but not when called by C# application running in VS2022 #27374

Possible solution (Extracted from existing issue, might be incorrect; please verify carefully)

I was able to fix this on my machine by simply running Update-Module -Name Az -Force. Sounds so dumb compared to the solutions above but it worked for me🤷‍♂️

Does the AssemblyLoadContext look into GAC for the assemblies? I would expect it will load the assemblies from the modules folders like the following:
False v4.0.30319 C:\PowershellModules\Az.Accounts\5.3.3\StartupScripts..\lib\netstandard2.0\Microsoft.Identity.Client.Extensions.Msal.dll
