Combining Word/Excel/PDFs or saving as PDF from word doc in Adobe Acrobat fails

We have an issue where our staff with active Adobe Acrobat Pro licenses and the app installed on their windows 11 laptop cannot combine or save files as PDF when sourced from Word or Excel.
An error is given relating to the PDFMaker

We can confirm that the add-in Acrobat PDFMaker Office COM Addin is Active and enabled.

We have tried repairing and reinstalling Adobe Acrobat Pro, 

and also enabling all Macros in Word/Excel with no success,
we have confirmed that the PDFMOfficeAddin.dll/PDFMExcel.dll is present.
We have also tried to save from Word using Save as Adobe PDF which works OK.
We also confirmed that the combining/conversion works OK via the browser version.
Can you suggest any other ways we can get this to work or what may be causing this issue?
