BUG: Null reference going back under hotkey page in Welcome Window

[turtley-turtle]

Checks

• I have checked that this issue has not already been reported.

• I am using the latest version of Flow Launcher.

Problem Description

If you go from page 3 to page 2 using the keyboard, null is referenced and a window with the title "Flow Launcher got an error" appears.

To Reproduce

1. Go to the 3rd page (Hotkey) of the first time window.
2. Click the hotkeys.
3. With your keyboard, make a pattern using the Up and Down keys.
4. Click backspace.
5. Then Flow Launcher will go back to 2nd page, and HotKeyControl cannot get Settings instance.

Maybe it's a rare bug, or a specific pattern i can't remember is needed. Maybe i specified the wrong pages
