Unfortunately Preview Has Stopped

This is what I get when I try previewing my app after the lates update (Current version is 0.10.0.6044.) How do I fix this issue (please ignore the background modal behind the main preview modal)

Here is the ouput from my fuse terminal. Notice the end line?

This is probably due to some stale files from a previous build. Could you delete the build directory and then try again?

You solution worked perfectly… Thanks so much.
