Challenger Captain reported while on final to an uncontrolled airport having an aircraft enter the runway opposite direction to their aircraft resulting in the flight crew executing a go around and returning to the airport.

Narrative

While on arrival into ZZZ we were vectored to ZZZZZ intersection by ZZZ. We called the field in sight and were cleared for the visual approach. This took us on a right down wind at 4000 ft. Which kept away and above all traffic. We made a right downwind call followed by a base and final call. While on short final at approximately 2 mile final; vision jet pulled out onto the departure end of the runway. There was also a disabled aircraft on the taxiway at the approach end of Runway XX. We executed a go around due to the aircraft on the runway. We did left traffic and landed without incident. There were also no other aircraft in either pattern. After we got to the FBO an older gentleman in the FBO questioned me as to why I did right traffic. I explained to him that we were on vectors from ATC. He seemed upset with this explanation. I then walked away as to not cause any further issue. The older gentleman was the owner of the broken down aircraft. The FBO attendant told me that most jets do exactly what we did.
