How was the object created? It looks like it has already been re-meshed into a quad mesh in another software. Is that true?
Do you use the paid, or the free subscription?
The paid subscription allows you to convert the original imported mesh into a solid using the "organic" option.
Which results in a smooth, non-faceted solid.
IF you use the free version only the "faceted" option is available an is by far the worst method to convert such a organic mesh into a solid body.
In that case I would use either Blender's quadri-remesher or Instant Meshes to remesh that mesh into a better quad mesh, import that into Fusion, convert it into a T-Spline and then BRep (solid).
The reason I asked the initial question is that the mesh already is a quad-mesh, but it's topology/patch layout is unfavorable for a direct T-Spline conversion. If the originating software has another remesher option, that might be an alternative.

Why can´t the irregular shape start behaving like any solid created directly in fusion?
.
Because the mesh appears to be a very thin walled object. That is what @jhackney1972 is trying to show in the screenshot and is also what I observe in Blender.
The organic mesh conversion method in Fusion simply ignores those almost duplicate vertices. In Blender i deleted them (merge by distance).and then I used the Qudri-Remesher.
That returns a super clean quad mesh that converts fine into a T-Spline and then BRep when imported in Fusion.
