I'm running Mac OS Catalina 10.15 and all of a sudden my favourite feature, Mission Control, has stopped working. It does not work with the touchpad gesture, touchbar, Apple Keybpoard or even my Apple Mouse. I've seen other articles for earlier issues where you update hot corners and/or use "Killall Dock" but none of these made a difference.

Any ideas?

Try to restart the Mac's Dock, follow this link fix the problem for me:

https://www.defaults-write.com/fix-for-not-working-exposemission-control/

To solve this problem apply the following defaults write command:
defaults write com.apple.dock mcx-expose-disabled -bool FALSE
Restart the OSX Dock:
killall Dock
