Qt Creator crashing on start-up

SPlatten

Last night I installed Qt Creator 4.14.0 with Qt 6.0.0, I then launched the MaintenanceTool and added 5.15.1 and 5.15.2. I left the installation overnight, when I returned there were no errors or warnings as far as I could see everything was ok.

When I launched Qt Creator it immediately shut down, I tried several times, same thing. I've submitted a bug report and thought I'd post this here to see if anyone has any advice because I cannot continue work until its resolved.

Bug report:
https://bugreports.qt.io/browse/QTCREATORBUG-25187

@KroMignon , thank you, it launched, but does the same, pops up in the launch bar then disappears very quickly.

I was in the Qt folder which on my system is:

/Users/sy/Qt

I then typed:

Qt\ Creator.app/Contents/MacOS/Qt\ Creator -noload all -load core

Result:

sy@Simons-iMac Qt % Qt\ Creator.app/Contents/MacOS/Qt\ Creator -noload all -load core
The plugin "core" does not exist.

However, I then tried:

sy@Simons-iMac Qt % Qt\ Creator.app/Contents/MacOS/Qt\ Creator -noload all -load Core

Which fixes the issue, core has to be Core. But the only tab showing is Edit, how do I fix?

When I tried to open my 'pro' file a dialog with an exclamation icon is displayed with the text:

Could not open "/users/sy/XMLMPAM/XMLMPAM.pro.user": Cannot open files of type "application/xml".

I then launched the Maintenance Tool then removed everything. Then from my profile I checked for files and folders and found .config, I went into this folder and found the folder QtProject, which contained several Qt Creator specific files, I removed the QtProject folder and its contents then reinstalled Qt.

That worked!

Thanks for sharing the bug report link.

Did you check the common settings as in https://forum.qt.io/topic/76015/qt-creator-crashes-after-startup ?

SPlatten

@koahnig , thank you, how do I do that? I've checked your link, all I have in is the "Qt Creator.app", how do I do the same with that?

KroMignon

@SPlatten You have to start QtCreator with command line arguments -noload all -load core

This will disable all modules and only load the core module
=> As usual you can check this in documentation ;)

SPlatten

@KroMignon , thank you, I realise that my question is how do I launch Qt Creator with command line arguments, since all I have is "Qt Creator.app" ?

@SPlatten

What is your OS?

SPlatten

@koahnig , macOS Big Sur Version 11.1

@SPlatten said in Qt Creator crashing on start-up:

macOS Big Sur Version 11.1

I've got Linux and Windows, but in documentation there is written:

On macOS:

    Qt\ Creator.app/Contents/MacOS/Qt\ Creator -noload all -load core
