Restart Word and check if the problem is solved.
If not only the input method switch in Word fails, it can't be switched in other applications (such as Notepad). Or some of the software's own shortcut keys and the system's default input method switching shortcuts conflict, we can change the system's default settings. Right click on the language bar and select “Settings”.
After popping up the "Text Service and Input Language" window, switch to the "Advanced Key Settings" tab. Select an action (such as language switching or full-width switch), and then click the "Change button sequence" button to enter the custom window.
Define a set of shortcuts according to your own usage habits and save the settings.
