Apple - Dock not restarting after killall Dock

tl;dr Run: killall 'System Preferences' > /dev/null 2>&1 && rm '~/Library/Application Support/Dock/desktoppicture.db' && killall Dock

For anyone who may experience this issue in the future, my issue was with the file located at ~/Library/Application Support/Dock/desktoppicture.db.

After doing some googling, I cam across the following two threads, here and here. Both of which suggest removing the desktoppicture.db with rm '~/Library/Application Support/Dock/desktoppicture.db' && killall Dock which solved the issue for me. You can read in more detail about the issue and proposed solution on the second of the two linked threads above
