Power BI Desktop WebView2 crash

I think I struck a similar issue, but my symptom was a "Black Screen of Death" as Power BI was opening a second pbix file. Both my monitors went black, and there was no response to any keyboard or mouse input.  The only thing I could do was hard power-off.

I turned off that preview feature, and it hasn't re-occurred since.  There was no webview2 crash file recorded.

I trust the Power BI product team will eliminate all these issues before rolling this feature out of preview. As it stands it might cause reputational damage to the product.
