We’re not sure if we have this completely identified, and we for sure don’t have a fix yet (https://mcneel.myjetbrains.com/youtrack/issue/RH-37382). The problem seems to have some relationship to OpenGL pipeline in wireframe views.
Here is what has been a workaround for a few users who are getting crashes on close. Set your display pipeline to Windows for wireframe views. The drawback to the workaround is you get some display wonkiness (https://mcneel.myjetbrains.com/youtrack/issue/RH-37387), but you shouldn’t get the crash.
