[deleted] when you get a chance, reach out to me on Discord 🙂 you can try to run php flarum migrate again to see if it'll create that post_votes table which looks to be missing in your situation.
Can you also check to see if you spot any of the Gamification migrations records in the migrations table? You'd need to delete those related records in that table in order to run any of the Gamification migration again from scratch (more specifically post_votes table first and possibly the foreign key constraint one)
