SU2-NEMO residuals stalling and divergence with nondimensionalization+AUSMPLUSUP2 #2717

Describe the bug
Good morning, I am trying to simulate a Mach 5 sphere using SU2-NEMO. In particular, I am using a quarter-sphere mesh with a supersonic inlet, outlet and a symmetry boundary conditions. I can achieve 1st order converge but I am not able to achieve 2nd order converge: I tried refining the mesh (uniformly and close to the shock obtained by 1st order solution), changing limiters (I tried all of them with different coefficients), changing scheme (at the moment the one which seems to work better is AUSM), but with no success. The energy residual goes down until about 1.7 and then stalls

Furthermore, if I use AUSMPLUSUP2 and any REF_DIMENSIONALIZATION, SU2 crashes without even doing an iteration (even with a good restart, e.g. first order solution). Actually I have noticed that the same happens if AUSMPLUSM and supersonic_inlet are used (or ref_dimensionalization is used).

I uploaded my config file and a couple of meshes I tried on google drive:

I am not sure this is a bug, so I apologize if I am posting in the incorrect section.
Thanks in advance!
