Xcode 5.1.1 crashes on opening

I have OSX Mavericks (10.9.4), Build - 13E28

I updated my Xcode from 5.0.2 to 5.1.1 (5B1008) from Mac App Store.

It was crashing when I started for the first time and created a new project using "Empty Application" template.

Then I cleared the preferences files (com.apple.dt.Xcode.*) in /Library/Preferences/ and ~/Library/Preferences/ folders

It worked for the first time.

When I tried to re-launch it again, it started crashing when I tied to open recent file from File -> Open Recents

Any help highly appreciated!

Thanks,

Dev.
