According to the lodestone, your character is still there but not in a free company. Maybe it needs you to login successfully to fully update the fact you aren't in a free company.

The crash is most likely because something in the surrounding area or in your character data is corrupt. You could navigate to the Documents\My Games folder, find your character folder and back it up by moving it to another location. This will reset all your hotbars, macros, HUD and other data but might stop the crash.
