@User_TPGJW This is quick fix for the issue, every time you reopen work , you have delete loadcount variable.

You can try setting up , Loadcount value as 2

@A.lee Yes everytime you reopen, Load count will be created, Delete Load count and open blank MS Word , Do not open any existing RTF template as your first word document

BIP Addins getting deleted from registry , create registry entry , follow instruction in attached excel
