How can I change input source in MacOS using Windows-style Shift + Command shortcut?

I've been using Windows for most of my life and at this point I've developed a muscle memory to use Shift + Alt when I want to change language.

Using Macbook Air With macOS Big Sur (11.6) as my personal laptop and I was frustrated to learn that I can't simply go to System preferences and assign Shift + Command to change input source... from what I understood you need a 3rd party tool for that.

• I've tried Punto Switcher but it crashes from time to time on my M1 Mac and looks like it hasn't been updated in a while.
• Karabiner is confusing to setup and it caused me a kernel panic once. =(

Is there another small (and preferably free) app that will allow me to assign key shortcuts to input source selection?

Solution 1:

I've found an app called CommandShift, it allows to change language using "Command+Shift, Option+Shift, Control+Shift or Fn+Shift" which is exactly what I need. It's free and gets the job done.
