[Bug]: In the version 2.3.0 impossible to add subscribers on the backoffice

[thorm42]

Description of the Bug

Since version 2.3.0, we had an error (error 500) when we click on "add" on the subscribers menu.

I saw when in this new version there was a refactoring of the subscribers code. Could this be the problem?

Thank you

Expected behavior

Have the form to add subscribers

Reproduction

1. Go to 'manager'
2. Click on 'subscribers'
3. Click on 'add'
4. See error

Version
