QtCreator help no longer available

Charby

I cannot use the integrated help with QtCreator anymore, when pressing F1 on any symbol, it shows "No documentation available".
From the preferences in Help, I have the default qch loaded (for instance org.qt-project.qtcore5.663) autodetected but in the help pane, the "contents" list is only showing QDoc manuel and Qt UI Tools and the "Index" is empty.

Sometime ago, I added a qch file I created using doxygen, despite the addition was working well at that time, I am wondering if this could have broken the help index somehow as the help system stopped working later on...

Here is my environment :
Windows 11 pro (10.0.22631)
QtCreator 13.0.2 and Qt 6.6.3 installed with the maintenance tool.

I have tried the following : remove QtCreator and reinstall with the maintenance tool, install QtCreator 14RC1, delete QtCreator keys in windows registry but without success.
I am running out of ideas, any help would be greatly appreciated.
Thanks.

Qt Creator is storing preferences in %appdata%/QtProject/qtcreator. You could try deleting / renaming the helpcollection.qhc to trigger Qt Creator to regenerate the help collection.

But, there is also C:\Qt\Tools\sdktool\share\qtcreator\QtProject\QtCreator.ini which contains the data from the Qt SDK informing for which Qt versions you have help installed.

Mine looks like this:

[Help]
InstalledDocumentation=C:/Qt/Docs/Qt-6.8.0/, C:/Qt/Docs/Qt-6.7.2/
InstalledExamples=Qt6 6.8.0|C:/Qt/Docs/Qt-6.8.0|C:/Qt/Examples/Qt-6.8.0/, Qt6 6.7.2|C:/Qt/Docs/Qt-6.7.2|C:/Qt/Examples/Qt-6.7.2/

[Plugins]
ForceEnabled=UpdateInfo, WebAssembly, WebAssembly

[Updater]
MaintenanceTool=C:/Qt/MaintenanceTool.exe
