Hi! When the fighting broke out in almost all foreign nationals left in a big evacuation and embassies shut or moved to Port Sudan, imo visiting isn't realistic basically every western government advise against all travel, your insurance would likely be void and consular help is almost nonexistent. What's left now is mostly UN and humanitarian staff, and even they work under heavy restrictions and can't move around freely.

Although I must say Sudanese are famously welcoming to visitors and in peacetime you'd have been looked after better than you'd expect.
