Fusion
"But as soon as I convert this object to a solid body - Fusion dies before my eyes"
This is exactly why this workflow is not recommended. Mesh bodies and Solid bodies are very different types of objects. Converting a mesh to a solid using the "faceted" approach creates one solid face for every mesh facet. This creates a VERY heavy solid body. So, your experience is exactly as expected.
Instead, if you want to use solid modeling, the best approach is a re-engineering process - use the mesh as a reference, and rebuild the model as a native Fusion solid. A lot of this depends on the nature of the model. Is it "organic"? (meaning a curvy model), then you would use T-Splines. If the model is composed of lots of planes and right angles, then you would use commands like Create Mesh Section and Fit Curves to Mesh Section to create sketches, and use Extrude/Revolve/Sweep, etc to rebuild the model.

That could not be further from the truth!
A Solid Body is comprised of usually trimmed analytical geometry (surfaces) and NURBS surfaces stitched into a BRep.
It is a mathematically precise description of geometry with topology and without a fixed resolution.
A scanned triangulated mesh has a fixed resolution and no topology (in a mathematical sense).
When you convert that mesh into a solid, each triangular mesh face is converted into analytical surface. That takes more data and more computing resources. When you use normal solid modeling operations, instead of dealing with just a few edges and surfaces, now Fusion has to calculate hundreds and surfaces and edges.
