Both extruder and heatbed turn on then off immediately

I just set my hot end to 230 degrees C and my heatbed to 110 degres C. The hotend was at 230 and the bed was at 92. I left the room for ten minutes and returned and both had turned off and had cooled to about 50 degrees C. Now when I turn them on, they show the target temperature and then immediately change to zero. Haev both mosfets failed at the same time?

Here’s an update. I flashed config file and everything went back to normal.
