[GIS] Why ArcMap 10.2 crashes when running model

Question

I`m running a simple model in ArcMap 10.2, which makes my ArcMap crashing (closing and then an error message pops in saying that ArcMap has encountered a serious error, and there is an option to report it to ESRI). Basically I want to rasterise some polygons, so I built a model: Iterate Feature Class> Project> Polygon To Raster. Does anyone have an idea why my ArcMap crashes when I run this particular model? (I do run a lot of different model, but have never encountered this issue before…)

Answer 1

You could try a few things to find the root cause.
First, can you isolate the issue down to particular feature classes? This might indicate that there may be an problem with your feature class. Second, try running the model in ArcCatalog and test. Third, try disabling any third party extensions you might have installed.
