Powerpoint Integration - Something went wrong

I am trying to run the Powerpoint integration from Power BI Service.  I am getting an error message different from the primary error documented at https://learn.microsoft.com/en-us/power-bi/collaborate-share/service-power-bi-powerpoint-add-in-troubleshoot.   I keep getting "Something went wrong"  with the following error details:

I have confirmed that I am running an acceptable Office build (

Microsoft® PowerPoint® for Microsoft 365 MSO (Version 2209 Build 16.0.15629.20200) 64-bit

)

I have WebView2

I am running Windows 11

All updates on both Windows and Office are current.

I added this Reg Key:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\WEF\Win32WebView2

The key's value should be set to:

dword:00000001

I rebooted.

I tried generating the PowerPoint link from Edge and from Firefox.

Thanks in advance for any help.
