What is this icon, please? (Canon g7x II)

[anna0051]

I brought my freshly bought Canon g7x mark II outside for less than 5 mins, afterwards I took it back to the house. Outside temperatures are around 0 Celsius or lower. When I turned it on, this icon appears whenever I try to take photos, and I can’t take photos with the flash on. Another thing it says is that AutoFocus is not working. Is it because of the fast change of the temperature? Will it work again like before, or should I take it to a professional?

Greetings,

What shooting mode are you in?  That icon looks like Background De-Focus.   See page 63 of your user guide.

What brand, size and type is your memory card?
