Hello!
Thank you for reaching out. Here are some steps you can try to resolve the issue:
Have you tried to check any settings related under Taskbar settings->Taskbar behaviors-> Notification area?
Try resetting the language bar settings. Press "Windows key + R" to open the Run dialog box, type "regedit," and press Enter. Navigate to "HKEY_CURRENT_USER\Software\Microsoft\CTF\LangBar" and delete the "Status" and "ShowStatus" values. Restart your computer and check if the language bar appears.
Note: Important this section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
Refer the article: How to back up and restore the registry in Windows
As a last resort, you can try recreating the user profile where the issue is occurring.
Regards,
Karlie
