[Identity] AADSTS9002313: Invalid request. Request is malformed or invalid.

I was getting the following exception when using DefaultAzureCredential:

Unhandled exception. Azure.Identity.AuthenticationFailedException: Azure CLI authentication failed due to an unknown error. CLIInternalError: The command failed with an unexpected error. Here is the traceback:
Get Token request returned http error: 400 and server response: {"error":"invalid_grant","error_description":"AADSTS9002313: Invalid request. Request is malformed or invalid.\r\nTrace ID: bb605d03-a3a5-44c6-95a7-76f523940000\r\nCorrelation ID: 54e3890f-28ae-44da-b69d-9ecdaa0b3091\r\nTimestamp: 2021-06-09 21:50:12Z","error_codes":[9002313],"timestamp":"2021-06-09 21:50:12Z","trace_id":"bb605d03-a3a5-44c6-95a7-76f523940000","correlation_id":"54e3890f-28ae-44da-b69d-9ecdaa0b3091","error_uri":"https://login.microsoftonline.com/error?code=9002313"}

It also repro'd using the following code:

var cred = new AzureCliCredential();
var token = cred.GetToken(new TokenRequestContext(new[] { "https://storage.azure.com/.default" }), default);

Or when running CLI command az account get-access-token.

I was able to fix it by running az login again. I have no idea what caused my az cli login to be corrupted (or whatever happened here).
