Helper IISession diagnostics error
Hi Matthew_Martell,
Thanks for confirming that the issue also occurs in the August 2026 release.Microsoft’s documentation explains that Start Diagnostics records evaluations triggered during actions such as Refresh Preview, while Diagnose Step performs a separate evaluation for the selected step.
Since the "0x80131623" error persists when using Start Diagnostics -> Refresh Preview, I recommend reaching out to Microsoft Support for further investigation. You can provide them with the affected Power BI Desktop versions, the error code, and the observations already confirmed in this thread.
You can submit a support request from Power BI Desktop -> Help -> Support -> Submit a ticket, or use the Microsoft Learn link below:

Thank you.
Helper IIUnfortunately I cannot submit support requests.
If I go to https://support.fabric.microsoft.com/ and click on 'Submit a ticket' it opens a link to https://go.microsoft.com/fwlink/?linkid=2230733 which simply takes me to the standard https://app.powerbi.com/home page. If I click on Support Centre from the help pane, it opens link https://aka.ms/contact-support which takes me to a page about government clouds: Sovereign Clouds | Microsoft Power BI
Basically, I just go round in circles.
