What does it mean when teaRank Rewards are paused?

Today I claimed some unclaimed rewards in my project, but when I claimed the rewards, I saw a message saying that teaRank Rewards would be paused. And it says that I need to stake a very large amount of TEA to resume these rewards. What does this mean?
I don’t know what it means to have a reward paused just for receiving it. (I received a reward for the quest, but the quest was not actually completed)
