Hi Mark,
Thank you for confirming that you have already tried the standard troubleshooting steps. Since Open in app worked previously, this may be an issue with the handoff between the browser, OneDrive, and the Excel desktop application rather than with the workbook itself.
Could you check whether the same behavior occurs with all Excel files in your personal OneDrive or only with this particular workbook? It would also help to try the file in another browser or an InPrivate window and confirm that the OneDrive desktop app is running and signed in with the same Microsoft account used in the browser.
When you select Open in app, does nothing happen, does the file simply remain in the browser, or do you see an error or permission prompt? That detail may help narrow down where the handoff is failing.
In the meantime, opening the workbook through Excel desktop or from the synced OneDrive folder in File Explorer is a practical workaround. Microsoft’s official guidance about opening OneDrive files in desktop applications is available here, although the documented Open in app process mainly applies to work or school accounts. Thank you so much for your understanding.
