az ppg create failing with any tags included in version 2.39.0

[JamesAlexHeller]

Related command
az ppg create

Describe the bug
Current version of azure-cli (2.39.0) introduced bug where any tag included seems to results in the returned error:
Parameter 'tags' must be of type 'dict[str, str]'

To Reproduce
Run the command: ppg create --resource-group <resource_group> --location <region> --name <ppg_name> --tags testtag=test using version version 2.39.0 of azure-cli. If the version is downgraded to any earlier version it works as intended.

Environment summary
Ubuntu 20.04.4 LTS, Python 3.8.13, pip 21.2.4, azure-cli 2.39.0

Additional context
including --debug flag produces the following output (some parts obscured)
