Hi Fridrick
Make sure your file name does not have any special characters such as slashes in it.
Make sure Excel is up to date. Go to the Excel menu and choose About Excel. Your version should be 16.57
Try making a minor change to the workbook, the use File > Save As and switch the format to Microsoft Excel Binary .xlsb The binary format can handle the widest variety of features.
