How can I cancel (abort) a shutdown when I see "A stop job is running..."?

I entered sudo shutdown -h now to shutdown my computer. Then, the "A stop job is running..." message appeared. I wanted to abort my shutdown and go back to appropriately closing the running programs... but I couldn't find a way to cancel my shutdown so all I could do was wait for the shutdown to continue. Most of the guidance I find online are focused on forcing immediate shutdown whereas I want to **stop** the shutdown. Is it possible to abort the shutdown in this situation? *Environment: Debian, XFCE, xfce4-terminal, Bash*
