It will make workbench.action.terminal.focusPrevious and workbench.action.terminal.focusNext not work.
My solution is to delete this two shortcut.
keybindings.json
[
{
"key": "ctrl+pagedown",
"command": "-workbench.action.previousEditor"
},
{
"key": "ctrl+pageup",
"command": "-workbench.action.nextEditor"
},
]
