Thanks for submitting your crash using the Crash Reporter. Using that information I was able link this with other reports in order to file the following bug report: JIRA [UE-26014] This will greatly aid our developers in pinpointing the cause of the crash, at which point an update will be added to this post.
In the meantime, here are some more things you can try:
- If any USB devices or other peripherals are plugged in, unplug them and try starting the editor.
- Try deleting your DerivedDataCache folder: (Users>Shared>UnrealEngine>[Engine Version]>Engine>DerivedDataCache) and restarting the editor
- If present, temporarily remove any projects from Users>[Your Name]>Documents>Unreal Projects (Place in a folder on your desktop) and restart the editor
-.
