Exception from HRESULT: 0x800A03EC on opening

Hi all,

I have a workbook that i have been working on for a while now that contains quite a lot of code, several tables and a lot of data. Recently on opening the file i have been getting an error (Exception from HRESULT: 0x800A03EC) when i click ok the woorkbook seems to be working just fine. Part of the code i have used is to hide the excel menus, and remove borders from userforms.

I also have a connection that just duplicates a table, one table shows all data and the duplicate is filtered.

I am running

Window 10 64bit
Excel 2016

I have attached a log file of the error.

Any body have any ideas
