My colleague tried to open a report from NAV 2018 on VS2017 and he had issues because the report only showed the XML view.
He was not expecting this and could not make sense out of it.
We searched for answers and saw
A great article from Kushal Pillay

and also Shashangka Shekhar

The steps were followed and the issue was resolved
