Printer stopped but is still powered on...?

I started an 11hr build and left for the day. When I came back the next morning, the printer had stopped at about 75% of the build but is still powered on, like it’s paused. The Fluidd tab in my browser says it’s lost the connection and needs to be refreshed, (refreshing does nothing) the touch screen is off. Is there any way to wake this back up and continue the print?

Does the touch screen come to life again when you touch it?
