Why does the app crash after signing the enterprise certificate?

[hamidalislam607]

Use unmodified source code from github. After xcode is compiled, app debug real-machine debugging can be used normally, and the ipa installed by UDID can also be used normally.

However, after the enterprise signs and installs the description file, it crashes after entering the app. What is the reason for this?

This is the log displayed on the MacOS console. Is it useful?
