UE4 starting stuck at 75%

The only thing I do is change



RicipesDataTable=LoadObject<UDataTable>(NULL,UTF8_TO_TCHAR("DataTable'/Game/ProduceSystem/RecipesList.RecipesList'"));

to another DataTable like



RicipesDataTable=LoadObject<UDataTable>(NULL,UTF8_TO_TCHAR("DataTable'/Game/ProduceSystem/RecipeList.RecipeList'"));

then I save and start the game in editor,it crashed.I can not start the ue4 success anymore,when I try to start it,the only log it shown is:


Log LogPython Using Python 2.7.14
Log LogTcpMessaging Initializing TcpMessaging bridge
Log LogUdpMessaging Initializing bridge on interface 0.0.0.0:0 to multicast group 230.0.0.1:6666.

I changed that line to the old version but still cant start ue4,also delete Binaries and rebuild.
