Engine 4.11.2 crashed very time I start it

The engine has worked just fine until I deleted one of my project. Then the engine just start to keep crashing every time I launch it. I attached the launcher logs. I hope someone know what is going on with my engine and that I don’t have to reinstall it.

Hi Xiao42,

The project you deleted may have been set to open to the project upon opening UE4.11.2. I recommended going to the Library tab in the launcher, removing the UE4.11.2 version of the engine and re-adding it again. If this does not resolve the issue, go to your Unreal Projects folder and right-click any uproject file to open it (in an installed version of the engine.) Once open, set that project to open automatically when the Engine version is launched under project settings and do not delete that project until you set a new project to open automatically.

Let me know if that works,
