Devexpress (v21.2): Could not find assembly Npgsql (during using 'DevExpress ORM Data Model Wizard')

Question

The database is Postgresql and I wanted to use DevExpress ORM Data Model Wizard v21.2. I got this error during the process:

Could not find assembly 'Npgsql'.

I have installed Npgsql already in my project module.

How can I fix it?
