Complete Kähler metric question for regular loci and complements

Let XX be a weakly pseudoconvex Kähler complex space. Its regular locus is denoted by XregX_{\operatorname{reg}}, and an analytic subset of a complex space is denoted by AA. Complete Kähler metric question. Does there exist an example for which XregX_{\operatorname{reg}} does not admit a complete Kähler metric? Furthermore, when XX is a weakly pseudoconvex Kähler manifold, does there exist an analytic subset AA such that XAX\setminus A does not admit a complete Kähler metric?

The question asks whether the complete-Kähler-metric conclusions known for compact or 11-convex weakly pseudoconvex spaces, and for complements of analytic subsets in those settings, can fail in the general non-compact case.
