Did you grab these logs right after a crash occurred? It looks like the editor was shut down cleanly based on the logs, so if you could reproduce the crash and then get the logs one more time, then we can have a closer look at what the error could be.
Since this crash seems to be related to blueprints in your project, it is likely that we will need to see the project. If you could, please zip up the project and provide a link to Dropbox where we can download it.
