Problem with mixed mesh (beam/solid/shell)

I have this structure which I have applied loads and constraints, however I have problem with running simulation to get deflection results. The FEA model consists of beams, shells and solids. I have problems with bonding mixed meshes (beams, solids, shells), running the FEA results in error, complaining about instability of the solution. To troubleshoot, As suggested by a training video, I have used the soft spring option, and there are no moving parts, but still the analysis doesn’t run without that option.
