Why my app immediately quit after open in iOS simulator?

Question

I installed Xcode(9.4.1) from App Store and create a iphone simulator. After that I tried to install some .ipa( https://github.com/OWASP/owasp-mstg/tree/master/Crackmes/iOS ) app to it but it immediately quit when I opened it. I tried couple app but the error is the same But when I wrote sample app on Xcode and build to my simulator it run very well.

Even if I try another iphone simulator or reinstall Xcode, I still get same error.
