PBR material manager

Hello, hope you're doing well I'm having some issues with iLogic scripts, specifically with accessing MaterialManager. The block in my script which calls them out is: ' Attempt to access MaterialManager Try oMaterialManager = oApp.MaterialManager If oMaterialManager Is Nothing Then MsgBox("Test Result: MaterialManager is Nothing after trying to access it.", MsgBoxStyle.Critical, "Debug: MaterialManager Test") Exit Sub End If Catch ex As Exception MsgBox("Test Result: CRITICAL ERROR accessing MaterialManager from Application: " & ex.Message, MsgBoxStyle.Critical, "Debug: MaterialManager Test") Exit Sub End Try When I run the script, I get the following error: I imported **Inventor** at the beginning of the script too I can share the entire script but what would be the cause for such a fundamental issue?
