Why is my UE4 version 4.13.1 failing to launch?

I have tried testing my game on android and have been having some issues… at one point I restarted the epic games launcher and now version 4.13.1 does not work. Every time I try loading it it says ‘failed to launch’… I have verified the files and I have reinstalled the version completely after removing it… it still will not launch. My project is made within version 4.13.1 and therefore I can not even load my project up… I tried converting the project to an older version but it doesn’t work (everything is just black).

Any ideas what I can try?

Thanks.

Just to add… when I try to launch my project in version 4.12.5 my map does not load… so I need to get version 4.13.1 working again before I can continue with my project. Any help would be much appreciated. Thanks again.

When I try to launch 4.13.1 I get error code LS-0013.

I would supply a log but I am unsure where that is located.

Start it via terminal.

Simply add >>log.txt and you got the output in log.txt

I followed that link and I launched the ue4 editor from the win64 folder… I then was able to open my project with no issue. I have made a shortcut to that ue4 editor so I will have to use that from now on as the launch in the epic games launcher does not work at all… it fails to launch version 4.13.1.
