Solution:
1, check the network and make sure the network connection is good.
2. Clear the background memory to ensure that there is enough running memory to run the game.
3. Download the latest version of the game again for installation.
Ps: In addition to the common reasons, some players will flash back because they can't see the archive. This is because different clients use the same file to log in different versions of the game. Just keep the client game version consistent.
