That should not create a problem. IF your battery was low on charge, realize that battery activity is reduced in cold weather and mirrorless bodies are a bit of a power hog so your camera may have been objecting to a drop in battery voltage. If the battery was at half charge or better, this shouldn't be the cause.
If that body is excessively temperature sensitive (component, connector, board trace) then that problem will manifest through cold soak anyway when in very cold ambient conditions. I would try to get this issue to repeat while it is still well within warranty and video it while glitching so that there is no question when you go through repair.
Your camera should be able to operate in temperature that is far colder than what is comfortable for you with the only expected issues being reduced battery life while operating in the cold. IF you take the camera from an extremely cold environment and then bring it into a warmer humid environment, then it is possible to briefly have a malfunction from moisture collecting and freezing on parts (like the mechanical shutter) but this is only happens under the most extreme conditions.
I have used Canon DSLR cameras for years in some pretty ugly conditions, one game I shot two years ago was 3F degrees actual temperature by the end of the event and I had a third body in my camera bag with a wide angle lens just for post game shots. That camera was turned off for the entire game so it would have been close to ambient temperature but it had no objections to waking up and working perfectly after the final whistle to end the event.
