8.0.18 A null was returned after calling the 'GetService' method on a store provider instance of type 'MySql.Data.MySqlClient.MySqlClientFactory'. (no replies)

I have a working Website with MySQL 6.9.12 and EF. I am in the process of trying to move this website to a MySQL Server running version 8 with .Net Connector 8.0.18.

I am getting the following message:
A null was returned after calling the 'GetService' method on a store provider instance of type 'MySql.Data.MySqlClient.MySqlClientFactory'. The store provider might not be functioning correctly.

I have updated all references, so what am I missing?
