Void in wallpaper behind corner

[SKYSUMMER]

Wallpapering for the first time, but there is an issue with a corner.

The paper is a paintable one with no pattern to match, just tiny string like lines.

The paper was put around the corner and I think it was not pushed right up into it in some places as it’s an 1940s house with terrible uneven walls.

There is now a gap (bridge like void between both walls) along the corner, the paper has dried and the next piece has been hung and also now dried.

How can we resolve this please, without removing it?

Thank you for your time

How long ago was the papering done?
Has it been painted?
Will it be painted?

Can you carefully run a sharp blade down the corner, carefully pull up the edges of the paper, and brush some paste onto the back of the paper?

It's never a good idea to paper round an internal corner, because of this problem. Always best to make a join in the corner.
