Hello. Today i was working on UE4, then the editor crashed by itself. Since, everytime i launch the project, it crashes giving only 2 lines callstack.
I took a look at the log and my eyes catched on this:

Is there anyway to fix this ? Other projects still open fine

After removing the plugins that were not compatible with 4.6, i successfully created a copy of the project and opened it. So i guess it has something to do with the engine or editor settings that could have been messed up.
A new version of the plugin i need should arrive soon. But just in case, i’d like to be able to open it in 4.5 again

Hi Darknoodles,

Are you able to Open UE4.5.1 and create a copy of the project that has the plug ins that are incompatible with 4.6. and then open that?

Also, can you supply a copy of the callstack from when it crashed as well as the following logs:

the “UE4.log” Located: Engine\Saved\Logs\

…and the “ProjectName.log” Located: ProjectName\Saved\Logs\

Thanks

I realised i didn’t expressed myself very well ^^. What i wanted to say is that i successfuly opened it in 4.6. It keeps crashing on 4.5.1.
I wanted to upload the log but it told me “No such upload” :-/
Project Log

the callstack is only that:
MachineId:A0A59DA44B439D0395517C868CDEA8BD
EpicAccountId:dc236bcf90a1432a82100005f180b13d

We apologize for the inconvenience.
Please send this crash report to help improve our software.

And finally, i searched for the UE4 log you spoke about, but can’t find any except this one:
UE4_Win64_MonolithicHeaders_Success.log that returns “Just a record of success.”

You can try this:

Close Unreal Engine altogether.
Go to your docs/Unreal projects/
Make a copy of that folder
In the copy go to the project file, select it, right mouse click and change Engine Versions to 4.5 as shown

Launch 4.5.1
Select open project and open the 4.5 version you just created.

Didnt work either.
But i did recover the project by trying to copy "DefaultEditor.ini and DefaultEngine.ini
Now it opens. Something must have gone wrong in the Engine ini.

Hi Darknoodles,

I’m glad to hear you were able to recover your project by creating a copy of the DefaultEditor.ini and DefaultEngine.ini. It sounds like one or both were corrupted.

Thanks for your feedback. This will likely help other experiencing a similar issue.
