My tiktok won't open

So I want to open tiktok this morning but the app open before closing itself, not letting me in. It said clear the cache because of a bug but..there's no cache to clear. I uninstall the app and reinstall but it still didn't work. It said try updating but it's already updated. I don't know what this bug is but it came out of nowhere. Any way to fix this or am I screwed?
