I upgraded your file to E+ 9.6.0 and it doesn't segfault there. I'll paste the log below, but I know what's going on.
Please add DesignDays to your OpenStudio model. Without design days added to your OSM, there isn't a Sizing:Zone object that is written to the IDF file. Yet, your PTAC has an autosized DX cooling coil. My guess is that E+ 9.5.0 did not properly catch that condition to handle it gracefully and segfaults as a result. 9.6.0 does it though.
I added design days to your OSM model to check, and it runs perfectly fine with them.
For completeness, in the ForwardTranslator (which translates the OSM to an IDF), a check is done in ForwardTranslateThermalZone.cpp, and a Sizing:Zone object is only added if: * The ThermalZone has at least one hvac equipment or Uses the IdealAirLoads * There is at least one SizingPeriod:DesignDay in your model
The interesting part of the E+ 9.6.0 eplusout.err is this one:
** Warning ** CalculateZoneVolume: 1 zone is not fully enclosed. For more details use: Output:Diagnostics,DisplayExtrawarnings;
** Warning ** GetInternalHeatGains: People="PEOPLE 13", Activity Level Schedule Name values

I don't have an answer, but can replicate what you are seeing running IDF exported from your OSM with EnergyPlus 9.5 CLI. Anyone familiar with Seg fault 11?
Not the cause for the seg fault but one issue in your model is the lack of surface matching. As a result an additional 35 surfaces that should not, are exposed to outside conditions. On top of that since all of those spaces are assigned to the same thermal zone the zone surfaces are nothing like a manifold geometry and isn't something EnergyPlus is accepting, could impact floor area, volume or other calculations. I had hoped this was causing the crash, but I saw same seg fault after running surface matching on your model.
With more testing seems related to Cycling PTAC DX Clg Elec Htg
David thank you so much for taking the time and helping me with this one.
Indeed when I removed Cycling PTAC DX Clg Elec Htg and instead added ideal loads to the model the simulation run normally.
If anyone knows about Segmentation fault: 11 please let me know because I still need to add some equipment for heating and cooling.
