I would also hold down the shift key when you open the app, open the form that normally opens in design view, check the code module has Option Explicit at the top and the click the compile option - that will highlight any missing references.
The other thing to check is if your version of Access 2016 is 64bit - if so, there are changes you need to make to any API calls made - again, ensuring Option Explicit is at the top of every code module and compiling will identify these
