xlswrite server threw an exception.

I have MATLAB 2013 on my Win 10 PC. Basically, xlswrite function is not working. It keeps displaying 'server threw an exception message. I have been using WPS Spreadsheets application and it was working fine so far. This error has been there only for a day or two.

I also checked the Add-Ins, and the only add-in I see is a TDM importer from NI (ExcelTDM.TDMAddin which I am unable to disable).
