From default startup I am not able to reproduce this. Can you clean up a bit objects from outliner.

Check if you can produce any effect with profile input in attached file.

My apologies for the delay, I just noticed your comment. I updated the post with a video, hopefully that will provide enough feedback.

@valera-8 , can you attach a simplified .blend file as I requested earlier?

This one is as simple as it gets...

Your file works for me as well..

I went back to my file, deleted all of the vertices and replaced it with a cube, reduced to a line and it works just fine. So the problem is with my mesh object.. no idea why, all I did is merge all vertices of a cube and then extrude. I think this can be closed..

I guess, yes. May be developers have better opinion on the report. So I will this on them.

I probably have the same issue and can reproduce it with practically the same setup. Although for me, wildly different meshes are created sometimes. This also seems to be non-determisistic, so if for example the geometry nodes modifier is disabled an enabled again, a different mesh is created. In some cases the mesh is a weirdly distorted tube, sometimes nothing is created, and sometimes even the correct mesh is created. Using the provided file "mesh_to_curve_bug.blend" by @valera-8 I can reproduce at least the last two cases by disabling and enabling the modifier multiple times.

My blender version is f9aea19d98.

This bug was probably fixed by 94084b2d3c.

@Quijx I can't reproduce the issue you mention. Please create a separate bug report for that.
