Hi, please check on amazon ses config panel if there are warning about another plugin loading the Amazon SDK, since the error is related to a missing class of the Amazon SDK and cannot be connected to WP 5.9.1 (or at least there are no clear reasons).

Hello Stefano,

You were spot on: an other plugin using Amazon SDK was causing the issue.
The newsletter plugin is working back as always: like a charm!

Thanks for this uber fast response!!
