The reason why "Genshin Impact" cannot be played on the tablet may be due to the following reasons:

1. Insufficient memory: Because the "Genshin Impact" game is large, it requires enough memory to run. If your tablet has insufficient memory, the game may not start properly.

2. Network connection problems: If the network connection is unstable or slow, the game may not start properly or run slowly.

3. Version compatibility issues: The "Genshin Impact" game requires a specific version to run smoothly. If the tablet's operating system version is too low, the game may not start properly.

It is recommended that you check the memory and network connection of your tablet, and try to update the game version or use other devices to play the game. If the problem persists, you can contact game customer service or technical support for help.
