PowerShot SX620 HS "Display will turn off any operation reactivates"

I keep seeing this message after 7 seconds of turning on my camera- "display will turn off any operation reactivates", and then the camera shuts down.  It's a new issue.. what should I do to prevent this from happening?

I just solved the issue by turning off the Eco mode!
