First always have your Transfer code binded and save its pass+code for overcoming worst case secenario.

Check there's any update in Qooapp/Appstore or not.

If there isn't any update try to clear cache= that doesn't removes your game data/internal downloads. Its clear data  which deletes all the game data.

Make sure your device lies within the minimum requirements of the game(even that can lead to some crashes and lags).

If its not only FGO which is lagging(i.e. other apps and games start to lag/crash) I recommend to factory reset your device(First backup your data....takes time+very hectic).
