To analyze your problem we need to know what implementation you're running, for which OS. But since you didn't say anything I suspect you may be using Windoze. ;-)
There is indeed a hotkey to switch layouts/locales, and earlier you probably didn't come across it. Find your "Region & Language" settings, then after some fiddling find the "Advanced key settings" tab of "Text services and input languages" (yeah, I know...). I turn off all the hotkeys except maybe something like Ctrl+Shift+# to change to a specific layout.
Odd thing though, is that Win+Space still changes layout on my Win10 computer. So there's another setting somewhere... but I forget where. Lol.
I'd recommend using PKL[eD] though! It's got many bells and whistles to improve your typing experience, lots more glyphs and images and Extend! Extend is great!!!
