There is a program written in vb.net. For several users, everything works fine. Several users get an error while working:

"System.ArgumentNullException: Value cannot be null.
Parameter name: type"

There are no references to a line of code.

It feels like the program cannot establish a connection with Catia.
Has anyone encountered such an error? How to solve it?
 
The error is too common.

Search for CreateInstance calls.
Rebuild application with debug info to see line reference.
