Can't Judge Second Prisoner

I have seen posts on the judgement bug, but I decided to post my own because it is a little bit different than what I've seen described before. After finishing the main story, I had two prisoners saved up to judge - Ser Ruth and Samson. I have already done the War Table mission to bring Samson to Skyhold. However, after judging Ser Ruth, I no longer have the option to sit on the throne for another judgement (even my journal no longer lists a judgement quest).

I have tried travelling around, switching thrones, doing a quest and returning, and loading the save right before I judged Ruth. So far, the problem keeps repeating itself. The only luck I've had is going back to a much earlier save (a while before completing the final main quest) and judging Ruth. After that, I have the option to sit on the throne and judge the next prisoner. However, I don't want to restart from this save point as I would have to redo like 15 hours of gameplay. I also don't want to ignore the problem because I really want to judge Samson to help give poor Cullen some closure!!

Has anyone else had this version of the judgement bug when dealing with multiple prisoners?

Thanks for any input!
