Xcode Project Can't Show Menu Bar

We have one problem when developing our project with macOS Big Sur system(Version 11.0 Beta). 

The details in .xib select item are missing, but we can see the outline of the drop-down menu. We could also click the button in the box(guess the position of the button and click), and then get the right result.

But, it’s very strange this problem only appears when we run the .app file in folder, if we run this project in Xcode, the details in box are normal.
 
Changing the dark or light mode on screen is no help with this problem.

Then, we found the log in console, there is little information about the "HIViewNewTrackingArea() failed with error -30599", so how to solve the problem?

The details in .xib select item are missing,

What is missing, EXACTLY ? Which details ?

How did you transfer the app from Xcode to Finder ?

What is missing, EXACTLY ? Which details ?

The wordings are missing, only a blank box is visible.

How did you transfer the app from Xcode to Finder ?

In Xcode, under the folder "Products", right click the .app file, select the "Show in Finder", then click it and run.
