Ctrl button switches keyboard layout after upgrading to Ubuntu 21.10

I've upgraded my Ubuntu 21.04 to 21.10. I remember responding that I want to use Control to switch languages. But then I realised that it's not very convenient. The problem is that I can't turn it off. Keyboard configuration is showing that the switch layout shortcut is different (Command + Space). Where can I fix it?

Solution 1:

In Gnome Tweaks, turn off that assignment to change to another keyboard layout. You will find the setting under "Switching to another layout" in the "Additional Layout Options" dialog ("Keyboard & Mouse" tab, button "Additional Layout Options"). Install Gnome Tweaks if you do not yet have it installed.
