Thanks for the report.
As a workaround you can set the Layer Height to .11. I got it to slice that way. (I left the model vertical.)
Someone from the Cura team will take a close look. I believe this behavior is being worked on by the Cura Team.

For developers: This dereferences a null pointer in SkeletalTrapezoidationGraph::collapseSmallEdges at quad_end->twin->twin = quad_start->twin;, because quad_end->twin = nullptr.
Increasing the integer precision from 1 µm to 0.1 µm allows the model to slice:
