Claudon–Höring–Kollár conjecture on projective varieties with quasi-projective universal cover

From papers

Let XX be a complex projective manifold with infinite fundamental group, and let X~\widetilde{X} be its universal cover. Suppose that X~\widetilde{X} is quasi-projective. Claudon–Höring–Kollár conjecture. After replacing XX by a finite étale cover, there exists a locally trivial fibration XAX\to A onto a complex torus AA with simply connected fiber FF. In particular,

X~F×CdimA.\widetilde{X}\simeq F\times\mathbb{C}^{\operatorname{dim} A}.

This is a structural conjecture for projective manifolds with quasi-projective universal covers; the source gives no resolution.
