Here I find two issues checking Body - BOPCheck enabled.

I fixed the errors by fully constraining the Sketch. I think the missing tangent was the issue. Now the body passes GeometryCheck, and slicing works.

Thank you, it's good to know that missing constraints can lead to problems during follow up operations, I was not aware of that.

It is not directly the constraints, but rather what they do to the geometry. Angles near 180° caused problems before, but usually with fillets, what I understand a bit better than the issue here.

Well, that was marked as an "opinion" from someone not being very familiar with it.
