CANT login into TikTok

I tried with my username, apple account, email Adresse and with my phone number but I always get this error when trying to log in: it’s just a white screen with nothing on it. I tried completely factory resetting my phone without loading a backup and I tried reinstalling the app and clearing the cache and everything. I also CAN log in on other devices and on my Webbrowser completely fine. It’s just on my phone apperantly. Please help ( I can’t attach a picture here but it’s literally just a white screen)
