How concerning are these cracks?

I just bought a home a few months ago built in 2013. Never noticed these and the home inspector didn’t say anything about them either. It’s really cold where I’m at and I’ve been hearing creaks in the wall every 30 minutes or so for the past month. I look up and see this crack where the wall and ceiling meet. It’s definitely big enough to fit a quarter through. Is this a concern? I don’t notice any damage anywhere else along the wall or house. Recommendations are welcome.
