When you change to a Korean keyboard by pressing Windows key + space bar, you should see the letter A and Korean icon beside the clock on the taskbar. Clicking Letter A will change the keyboard to Hangul.
I will attach a screenshot of it so you can have a reference.
Try to uninstall the Korean language then restart the system. Reinstall it after the restart.
Let me know the results afterward.
Hi bro,
Same Issue. Your method has not helped.
