Crash report

While working on my project that message appeared ,and i clicked the send and close button … but still remaining ,any help!

This is a generic window that appears when the editor has crashed. This might be due to a number of issues. It could be that there is a bug in the editor, however it is far more likely that you did something that made it crash (for example dereference a nullpointer in C++). If this happend after you compiled something the code that you compiled might have a bug. If you want to get help here, you will need to have an idea of what caused this crash (you can check the logs in “YourProjectFolder/Saved/Logs/”, maybe that’ll give you a clue). This screen ultimately only tells you THAT something went wrong, not WHAT went wrong.
