This has happened to me 2 different times. I found that I could start the truck in neutral and let it idle for 30 minutes. Then put it in gear and start it and it breaks free. It may take longer in your colder weather.
It seems the materials in the clutch disc will stick to the flywheel when put away warm and left to sit for an extended time. Putting heat into the clutch disc softens the material and lets it release.
I've tried to remember to put a 2x4 against the seat and the depress the clutch pedal when I know it will sit for a while
