Downloading and installing from App Store would fail?

I just release a new version of my app. But unfortunately the new version app crashes every time it launches.

So I used a file tool, which could browse, copy and export files inside iPhone, to export the .ipa file of my app that crash.

Then I find the archive that submitted to App Store by Xcode, extract an .ipa file from the archive. And if I install the ipa file with the tool I used, it would launch and work properly.

After I got 2 ipa files, I unzip them and use some file merge tool to check the difference between folders and files in that two ipa files, finding that the failed one seemed not to be updated. Some new-added file didn't exist and some renamed file didn't change their names.

So I doubt if the process of downloading and installing app from App Store go wrong, though it sounds like impossible.

There is part of crash log on my device. But I can barely read useful information from it.
