successfully using 4.13.2 for quite long time already.
prequel: after editing some AnimGraph StateMachine, and compiling it - the engine crashed. i’ve reopened it and made the same changes, but this time saved before compiling; compilation crashed the engine again and since then:
launcher stops loading after “initializing… 95%” and simply ends the process without any errors or notifications, like
editor would start in a moment, except it doesn’t.
log provided.

bumpy bump
-Back up your project folder to an external device, and do this throughout your development process.
-remove your saved and intermediate folders within your project folder.
-With the Epic launcher verify your UE4 version under the drop down menu.
didn’t help unfortunately 
Hey -
I’m not sure what you’re trying to do, but it sounds like the changes made to your AnimGraph are the issue. You should be able to remove the AnimGraph .uasset from your project’s Content folder and then reopen the project. Once you’ve opened the project, you should be able to move the asset back into your content folder and revert the changes that had been made to get the project to load normally again.
Cheers
thanks! it have worked and i can now launch the project.
but when trying to open the AnimGraph, the engine gets the same bug as described in the topic. is there any way to at least delete a section of that AnimGraph manually (text editor or such)?
(the state machine)
Unfortunately an AnimBP cannot be edited outside of the editor. If you do not have a backup copy of the asset, the best solution would be to simply recreate the blueprint itself.
