Unsolved Fail to open qt designer on macOS Mojave 10.14.6 with error: "Qt Designer quit unexpectedly."

[Camelia]

Hi I would like to install qt designer on macOS Mojave 10.14.6.

However, met the error “Qt Designer” can’t be opened because the identity of the developer cannot be confirmed."

I checked my security&privacy setting and allowed the app "Open Anyway".
But cannot open it with error message "Qt Designer quit unexpectedly."

Do you know how can I get it installed?

Hi and welcome to devnet,

You should have gotten a report window showing the stack trace. Can you share it ?

@SGaist Hi thanks for replying!

The report is as below:

What version of Qt are you using ?
How did you install it ?

[Camelia]

@SGaist not sure about the version. But I downloaded it from this website: https://build-system.fman.io/qt-designer-download
And a friend downloaded it here as well. She successfully installed it on macOS Mojave 10.14.4.

Then, please, try the official package.
