Can't overwrite existing app with new version

I downloaded an app from the official staging of ​​my company, but it cannot overwrite the old app downloaded from the Apple store ( it was possible before ).

What are the reasons for this situation?

What should I do to get normal coverage?

I only modified the "Bundle display name" in the new application. The original setting was Boolean: No, but this setting will cause the application name to be displayed as "Project file name" in subsequent iOS versions. The text written in my Chinese language file will not be displayed.

The new application is compiled with Xcode15.3 and the old application is compiled with Xcode14.1.

Your answers are all helpful to me.
