Drywall tape peeling along ceiling edge
I don’t see any evidence of repair so it may warrant a little more investigation.
In the Pacific Northwest we have multiple possibilities that could cause this;
Carpenter ants.
Termites.
Wood rot.
I like to use metal inside corners. Sand the texture mud the corner in and retexture.
Since this looks new and things may still moving I would put a scale or ruler up there and take a clear photo. Wait a 6 months and re measure. If no change repair.
If there is a change .
Be on the lookout around the home for carpenter ants and termites.
This new of construction should not have issues yet but look for water running down walls (plugged gutters) things that could start wood rotting)
If you haven’t noticed any of our big 3 and the crack has not gotten worse now would be the time to repair.
It could have just been “New house settling” since the structure is not very old and we have had some high winds lately.
