Hi,
Please check the following thread:
Hyper-V - Unable to Create External Virtual Switch
Please note: Information posted in the given link is hosted by a third party. Microsoft does not guarantee the accuracy and effectiveness of information.
It states in the doc you give: Original product version: Windows 10 - all editions, but the fix cannot work for your system.
For now I suggest you use the builtin Windows Feedback Hub app within Windows and provide feedback about this issue so that Microsoft can start working on this issue.
Thanks for your time!
Best Regards,
Mico Mi
