Answer 1

The shortcut you are giving for Launch calculator is for gnome-calculator if you installed it via APT.

Below is the path of executable file of snap version of Calculator that is pre-installed with Ubuntu 18.04 which can be used to set shortcut as well.

/snap/bin/gnome-calculator

To use Ctrl+Alt+5 either install gnome-calculator from APT or create a custom shortcut for snap version of Calculator.

I have customized for both

Answer 2

Most shorter way is reinstall default snap calculator to deb:

sudo snap remove gnome-calculator
sudo apt install gnome-calculator

Then manual shortcuts from Settings starts working.

Did you check your Shortcuts (Ctrl+Alt+5) is used for another Keyboard Shortcuts? Because when I set Shortcuts (Ctrl+Alt+5) for Gnome Calculator (on Ubuntu 18.10), it's run normally. keyboard shortcuts for gnome-calculator

Maybe you need to "Reset All..." and set Shortcuts again.
