In order for us to provide better support, we need to see the log generated by citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File

This isn’t really a Citra related question. You’d be better off asking this somewhere like Project Pokemon’s forums. Maybe this is possible with PKHeX?
