    I downloaded one pre-compiled version of gn, 0.4.1. But the output says: "...but required exact version '6.8.1'. The question is: Where can I find a version 6.8.1? The link above provides latest version 0.4.1.

    Hi, Just don't play with LD_LIBRARY_PATH unless you have very good reasons (this one is not). Qt Creator is self contained and you are pointing it to a different version of Qt than the one it's bundled with. If you modified that variable in your bashrc (or equivalent) you are also forcing all your system's Qt 6 applications to use that version of Qt rather than the one provided by your distribution which is not at good idea either.

    @SGaist - Doesn't sound silly to me at all. About a year ago I worked with Support to consolidate all of my Qt activities under my current email address. I thought that included my installation credentials and I'm pretty sure I have used the Tool several times since they helped me with the address. I have reached out again to see if I missed something then. Thanks for your input.

    I hat such errors appearing suddenly also, and what helped was to put the build directory next to the source directory, not below the source dir as QtCreator does nowadays. For me, that was with make projects and Qt 5.15. Regards

    Yes it return a valid pointer qDebug() << selectionModel(); output QItemSelectionModel(0x6e39580) qDebug() << selectionModel()->model(); output QSortFilterProxyModel(0x6e34008) Debug Assertion Failed! From the stack trace, I deduce that errors occur when the QModelIndex is removed [image: 2121c0df-c32f-430e-af36-b5b0ad13456a.png] I'm not sure if this helps, but when I manually set the selectedIndex to (0, 0), the error doesn't occur.

    Hi, You should rather bring this question to the development mailing list. You'll find there Qt developers/maintainers. This forum is more user oriented.

    For some reasons I had to click on "Re-configure with initial parameters" and now the variables have the correct path.
