Launchpad not working - Mojave

Hi, I have updated my MacBook Pro to Mojave and two things have happened:

1. I can see the Launchpad icon on the dock but it doesn't show the launchpad when I select it. That is, no Launchpad window opens.

2. I cannot swipe to the right to display the calculator/other desktop.

I have looked at previous fixes involving the Library/Application Support/Dock Folder but there is no dock folder anymore.

Thanks
