If the Dock fails to relaunch after killing it, is there any way to force it to relaunch? Every now and then I encounter an issue or bug in macOS that requires me to kill the Dock process. (For example, oftentimes some of my keyboard shortcuts for switching spaces stop working and the only way to fix it is to restart the Dock.)

However, sometimes when I kill the Dock it will fail to automatically relaunch, leaving my system in an unusable state. Aside from something like rebooting or logging out of my user account and logging back in again, is there anyway I can force the Dock process to launch again?
I have finally found the answer to this question. If the Dock fails to relaunch, execute the following shell commands:
launchctl stop com.apple.Dock.agent
launchctl start com.apple.Dock.agent

The second command may not be necessary but should probably be included anyway just to be safe. This is probably a much safer way to restart the Dock than simply killing it.
