The app on the emulator cannot be opened, and there is no specific crash problem. do not know what to do.
However, there is still a solution, which is to use XCode to run the project and view the output
Open the project with Xcode

By analyzing the above error log, we can determine that the problem is because the application cannot be run on emulators below 14.
