--verbose on my installer causes Finish page doesn't come

I'm using QtIFW 4.7 with Qt 5.15 on windows 11 to build my installer.

If the installer.exe is launched directly, it works well. But if I launch it from command line with --verbose argument, the installer will struck at 100%, 

the callback for page is not entered

```
the Controller.prototype.FinishedPageCallback = function() 
```
 
the callback I wrote is called
```
installer.installationFinished.connect(Controller.prototype.installFinished);
```
 
and the last lines in console is
```
[29223] Writing maintenance tool.
[29825] Wrote permissions for maintenance tool.
[30050] Maintenance tool hard restart: false.
[30059] Installation finished!
[| 100%]
 
```
 
I need some suggestions to debug this.
