Just got exact same thing. If I have a normal Excel .xlsx file open and I start WD, all is fine. Then in Excel I try to open the VBIDE and Excel crashes. Alternatively, if I have a workbook with macros (.xlsm) open (VBIDE not open) and I start WD, Excel crashes. WD 3.5.1, Excel 365 desktop.
Commandline parameter not working
