Excel Copilot WebView2 crashes when rendering download links - Bug
Environment: Excel for Microsoft 365 (Desktop) Windows 10/11 - Enterprise account Issue: Excel Copilot's WebView2 panel goes completely black/blank when attempting to render download links for files generated in the Python sandbox. Steps to Reproduce: Open Excel with Copilot Ask Copilot to perform any task that generates a download link (e.g., "create a test file and give me a download link") WebView2 panel turns black immediately What I've Tried: Clearing WebView2 cache at: %LOCALAPPDATA%\Microsoft\Office\16.0\Wef\webview2\ Copilot works normally after cache clear UNTIL a download link is requested Issue is reproducible every time Workaround: Asking Copilot to write results directly to sheets instead of generating download files works fine. This started after an Excel crash during a Copilot session.
copilot app is unable to edit an excel file and save a new version
I asked copilot to review an excel file I created and add worksheets with dashboard etc; it does the analysis, suggests the solution but when I ask to save a new edited version comes up with all kinds of limitations.. example of message : I need access to the physical workbook file in the execution workspace, not just the extracted workbook content that I can read. What I currently have is access to the contents of "book2" , including all sheets and rows What I do not have is a file path that allows me to save a modified workbook and return a new Excel file. This is exactly the distinction you were asking about earlier: ✅ I can inspect and analyse "book2". ✅ I can design the full V2 architecture you specified. ❌ In this session I cannot yet create and return the modified .xlsx because the actual uploaded file is not available in the workbook-editing workspace. I save files on OneDrive and have MS365 Family subscription , similar limitations with all MS files is it a licence issue?
