After the Windows 11 update I can't export in Excel an IFS Business Reporter file.

I usually go to the 'Manage Reports' function in the tool bar and then "Export" the report. Which then saves the file as an excel file.

I have been using this method successfully for years until my laptop has gone through the Windows 11 update. I am now receiving the below error message: 

Any idea how to resolve this issue? Thanks

The error details as follow:

System.Runtime.InteropServices.COMException (0x800A03EC): Excel cannot open the file ’tmp30AB’ because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file.
