''RUN TIME ERROR 13 TYPE MISMATCH'' WHILE WORKING MACRO ENABLED EXCEL FILE

Dear All,

We have been using a macro enabled excel workbook with OFFICE 365 and it never use to bring a problem until at the start of FEB 2020 it started giving me error 

Run time error 13 Type Mismatch.

This is a work book provided by the government so it cannot be edited in its coding sense only data input can be done for uploading purposes. 

Please note i have already run an update and also run repair on the app. through control panel 

I would like OFFICE 365 experts to assist me with if there were any updates that were done and might have started the error etc.
