This sounds like a storage error, as in the game hasn't downloaded the assets it needs to keep going. You may want to check your storage, free up space, and potentially redownload the game if freeing up space doesn't work (if doing so make sure you account has been saved somewhere) to see if it downloads the assets properly.

If none of these things help I would recommend contacting support.
