Token authentication breaks when using certain commands

[insomniacc]

Describe the bug
Running the following command breaks my authentication I'd previously configured with Connect-MgGraph:

Invoke-MGGraphRequest -uri "https://api.accessreviews.identitygovernance.azure.com/v1.0/identityGovernance/accessReviews/definitions/<AccessReviewID>/instances/<InstanceID>/contactedReviewers/`$count"

Subsequent commands using Get-Mg commands just fail with the following output for example:
Get-MgIdentityGovernanceAccessReviewDefinition_List: The server responded with a Request Error, Status: NotFound

The only way to proceed is to re-run Connect-MgGraph.
It seems that the authentication is being broken and the commands do not gracefully handle the issue / complain about authentication in an explicit way.

Expected behavior

1. if authentication breaks, subsequent commands should throw an exception/error related to authentication.
2. Issuing a get method with Invoke-MgGraphRequest should not break authentication set by Connect-MgGraph

@insomniacc what I've noticed is that the base url (https://api.accessreviews.identitygovernance.azure.com/v1.0) you are using is cached after calling an API with Invoke-MGraphRequest and subsequent cmdlet calls append that base url to the API path associated with a cmdlet.

However, when you call Invoke-MgGrphRequest with graph's base url (https://graph.microsoft.com/v1.0) within the same session, you won't get an error for subsequent cmdlet executions. Therefore, it's not really an authentication issue.

I'm not sure why this has been marked as author feedback. What exactly is it you need from me? The bug is outlined in my original comment and also confirmed by timayabi2020 please can this be assigned to someone to fix?

Having stumbled on the same problem: Invoke-MgGraphRequest -Uri <some_URI> overwrites a global / environment variable so that subsequent calls to other MgGraph cmdlets use <some_URI> instead of the standard https://graph.microsoft.com/v1.0 base URI
