Export orders bug (related to PHP 8?)

Dear support,

We bought Store Exporter Deluxe (Version 5.2.1).
Everything was running smoothly until we moved to PHP 8.
The “Export Orders” stopped working.
It triggers the following error message: TypeError thrown: array_map(): Argument #2 ($array) must be of type array, string given

Are you aware of this issue?
Do you plan to deliver any update soon?
Thank you for your help!
