Epic Launcher crashes after changing to using source version of UE4?

Hi!

I downloaded the source of the engine through GitHub, compiled it and run it once. Since then the Epic Launcher crashes pretty much directly after the GUI is displayed every time. No matter if I run it directly from windows or by starting a project. Even for projects not using the compiled source version. Any ideas what may cause this issue or how to resolve it?

Hi undercover,

Try the steps in this section of the troubleshooting guide.

If nothing works, then follow the steps here to generate your Debug Logs. Post them here, along with your Dxdiag (system specs).

Thanks I will look into it.

Couldn’t get it to work following those steps. Reinstalled the launcher and now it seems to work again. Think there was something with the default file associations or something but that is just speculations.
Thanks anyway!
