Solution 1:[1]

VB Solutions runs from "YourSolutionFolder"/Bin/Debug or "YourSolutionFolder"/Bin/Release depending on your configuration.

Hence your rpt file must exist in those folders.

Copy your ClinicianList.rpt files to above folder and then reportDocument.Load("ClinicianList.rpt") will work

Solution 2:[2]

Try this below code 

reportDocument.Load(Server.MapPath("CrystalReport.rpt"))
