Has anyone ever seen this kind of response from reportviewer? (see below)
I am trying to integrate reportviewer into an existing web .net framework application and am now beating my head against a wall.
The reportviewer works fine in a new project but does not work when I integrate it into an existing project.
I used the following url to install the report viewer both in vs2019 and in vs2022 with the same results:

I have no problem designing the report creating a .rdlc file and connecting it to the reportviewer and SqlDataSource.
My suspicions are that I have a package installed that is conflicting with the reportviewer.
