Large areas of relatively featureless wall and ceiling can be tricky.

Did you try using the vertical line tool on this pano?

Try this shooting pattern: 6-around at about -10 degrees pitch (so that the outer edge of the central rotator of the pano head is just in the frame); and 6-around at about +50 degrees.

I know it may sound a bit unusual but get very good stitching when shooting even the smallest interior pano with this pattern using a Nikon DX body and the 10.5mm FE lens..

Of course I'm assuming you are using a proper pano head and that the camera/lens is correctly set at the NPP.

Remind me - what pano head are you using?

Especially shooting indoors a precise alignment of lens/camera/head is essential. And a correct leveling also helps a lot in saving post-correction time.

I also suggest to shoot in portrait-mode 6 horizontals + 1 Zenith + 1 Nadir in small spaces. Shooting Nadir+Zenith helps in closing the sphere and having low distortions. Shooting an extra Nadir by hand or a slanted tripod to avoid seeing the head´s base or the tripod-legs in the Nadir image helps alsi in small rooms. You just pull the tripod aside and tilt the camera straight down to photograph the space the tripod covered before - that´s easy done and adds perfection to your image.
Given your head´s base is very small you also can retouch the Nadir hole easily . . that depends on the situation.

As Andrew already mentioned: use the vertical line tool to correct verticals.

Well - then you misaligned your setup. The pattern shows that stitching is geometrical corect (the borders of the black areas are symetrical).
So the issue must be with the alignment of your lens-/camera-/head combinbation.
