This is the Qt Creator version, is not relevant here. Qt Creator is "just" an IDE. What you have to specify is:

which OS you are using
which QT Kit you are using

It seems that the Qt Kit you are using do not have been build with QtLocation support.

-1: erreur : Project ERROR: Unknown module(s) in QT: location

Did you build yourself the Qt Kit or do you use an official Qt Kit?
=> AFAIK, QtLocation is available since Qt 5.5.

I'm on Windows 10, i use the last qt version (i don't know the version and how i can verify)

For the install, i use the default option "Design Tools" + "QT 6.1 for desktop development" + "Qt 6.1 for mobile development"

Qt 6.x is a "work in progress", many Qt 5 modules are not all supported or have moved/merged to/with other modules.
Qt Location is one of the modules which don't have any planned porting date.

I don't know if it will be ever available in Qt 6.

This is a bad news.

I left Qt since a while but today I tried to move back but the first thing I struggled with is building my old Android app using Qt 6 which uses Qt Positioning!
May you please ask on behalf of one the community what if QtPositioning & QtLocation will be supported in Qt 6 or not?
It's vital for me to know the future of Qt 6 because Qt 5 LTS will end on 2021-12-05 so I've to make the decision to keep with Qt or leave it once again.

Take a look at this Qt blog entry: https://www.qt.io/blog/qt-6.2-vs.-qt-5.15-the-feature-parity-comparison
