Use Slot 24 to choose which route to follow. I am going to leave the rest of my saves in case you find something you might use.

I accidentally locked myself in church route because I did not know edelgards requirements so I managed to edit the savefile to repeat chapter 10 and start through edelgard route, this might cause bugs or stuff like that.

At the moment of writing this I'm currently on chapter 13 without any issues yet. I hope you enjoy.

Sincerely
