Editor launches, but quits without displaying an error

I converted my project to 4.11 from 4.10.4. No specific error is produced. The splash screen shows, hits 100%, and just closes. The log file contains nothing about the fatal error either.

Hello,

Does this issue occur in any project that you try to convert from 4.10.4 (i.e. a clean project with no additional content)?

Are you attempting to open a copy or are you converting in place?

Not any project, but in particular this one I am working on. I copied project first and it can actually be converted back to 4.10.4 and work fine.

Creating a new 4.10.4 test project: It launches, builds, and opens fine in 4.10.4. I closed all the editors, converted it to 4.11.0, and rebuilt the solution files. Reopen the project in UE 4.11.0, says the *.dll is out of date as expected and it needs rebuilt. Result: “Test410 could not be compiled. Try rebuilding from source manually.” This is because the *GameMode.cpp file did not override any methods. Fixing that allows it open in UE 4.11.0 after rebuilding in Visual Studio.


Additionally, the following error occurs when attempting to create a brand new 4.11.0 Test project, C++ blank, maximum quality, no starter content.


The project could not be compiled. Would you like to open it in Visual Studio?

This might be your solution

I have attempted to reproduce the error you are seeing when you create a new C++ project in 4.11, but I’m not seeing any errors appear.

Do you have any of the default plugins disabled in your original 4.10.4 project?

Nope. I have left all the plugins alone. I have also tried reinstalling the 4.11.0 engine and running a verification against it.

Are you using any sort of antivirus software that could potentially be interfering with the files?
