Windows 10 input method cannot switch "Chinese Simplified" input method in the game

When playing Minecraft for Windows 10 in Windows 10, I switched to the computer desktop halfway and then switched back to the game. It would happen that I could not switch to the "Simplified Chinese" input method in the chat bar, only English can be input, and pressing the "shift" key was also No effect, switch back to English input method, and then switch to "Simplified Chinese" input method is still useless, hope to get help
