Opening an Excel Workbook from Files, causes a blank workbook to launch as well as the one selected

Hi All,

I am new to Teams, so still trying to figure things out.  I have a fairly consistent problem when opening Excel Workbooks directly from my team's page.  When you right-click on the workbook and select "Open in Desktop App", Teams will launch the workbook just fine, but it also opens a new blank workbook.  If you try to close the blank workbook, it will also close the workbook you were trying to open.

Just wondering if this is a known issue and if someone can point me to where a blog or tech post could cover the solution.

Thanks!
