I don't see any info to work with.
If you think it's exactly repeatable quests that breaks profiles - just clean them, find your profile in user/profiles, open it Ctrl-F `RepeatableQuests` and make them empty, like "RepeatableQuests":[],
Sorry for the reply spam, I was able to change the profile end times from a huge number back down to 1440 and it's working again, thank you, I thought I was going to have to restart.
