Visual Studio is crashing while open Flightdata.cs

Hi, I downloaded mission planner latest version from github. And ı made git submodule update --init --recursive.ı opened MissionPlanner.sln file and ı start MissionPlanner at relase and Any Cpu .Okey missionplanner.exe worked. No problem so far. But visual studio crashes when I open flighftada.cs file to customize. There is no problem with other files, they open and there is no crash. Just while open flighdata.cs file visual studio is crashing. I have been tryıng to solve thıs problem for a week. I have deleted, reinstalled and repaired Visual Studio many times. How can I properly download the latest version of this missionplanner and edit it?
