Crash after building lighting

I have Win 7 64 bit.
After starting the lighting bake, the swarm window comes up

Also this progress bar:

Then UE4 crashes.

Any solutions?

The Swarm Agent log looks like this:

Problem solved! I have hungarian characters in the name of the user / documents folder (I have a hungarian Win 7).
Saving the project elswhere solved the problem.

Thanks for the follow up. We have a bug report to track internally. We’re currently only supporting Korean localization and character support at this time, with more languages to come.

Hi, I just fixed this bug and it will be included in the 4.1 update coming later this month. 4.1 will correctly handle Unicode folder names for the project file.
