Unable to connect to Portal for ArcGIS using ArcGIS Python API

We switched Portal for ArcGIS security from SAML based identity provider to use Integrated Windows Authentication. After this change I am unable to connect to the Portal using the ArcGIS python API. I can sign into the portal in ArcGIS Pro as well as using the browser. However, I am not able to connect to the portal within ArcGIS Pro Python window. I get the following error message (Attached screenshot) when attempting to connect to the portal using the API.

I have seen a BUG related to this: BUG-000108063

I tested a few python environments in conda and was able to connect to the portal. However, the version of ArcGIS python API has to be 1.2.4 or lower. Unable to connect with a newer version of the API.

Also found a few post talk about this error related to specific version of pywin32 module and recommended using winkerberos. Haven't got success with this approach as well.
