Thanks for the report. Can reproduce crash.
Not a regression, crash is reproducible since Mesh to Curve node landed in master.

I simplified the file a bit to this:

T95901_simplified.blend

Not sure where to go from there. The bug seems to be somewhere in triangulation code. It's quite sensitive to the input, so small changes in the inputs can stop making it crash.
@howardt can you have a look at this?

Hard to say, but this may be related to #95518.

Thanks for looking into this guys. Not sure this is helpful, might be a separate issue, or not an issue at all. But starting with a holed mesh and trying convert the edges into curves then filling give unexpected results. The resulting faces seem to have no Z depth. If this isn't helpful just ignore.

The problem is basically that my delaunay code expects there to be faces in the input if the output mode "VALID_BMESH_WITH_HOLES" is used. I'm not sure what the user was expecting here -- a triangulation of the convex hull of the segments that includes those segments, and then dissolving non-input edges inside as much as possible while leaving valid bmesh? I suppose I could add that output mode, but none of the current output modes do that.

Of course it shouldn't crash and I'll fix that, but the current output will just be a set of points, no faces, because there are no input faces to preserve in the output.
