"no suitable kits found"

[xqz5222]

I installed Qt by installer download from this link https://www.qt.io/download-qt-installer-oss?hsCtaTracking=99d9dd4f-5681-48d2-b096-470725510d34|074ddad0-fdef-4e53-8aa8-5e8a876d6ab4. The installer used to has the option to install desktop development like below.
However, recently the installer I download only has a design studio option and after I install it has a "no suitable kits found" issue when I try to create a new project.
Thanks for helping!

@xqz5222 what did you do next?
6.1 is kind of lower version in Qt6. Maybe better to use the latest Qt6. Check custom installation in your first picture.

@JoeCFD Thanks, the first screenshot is from the internet. The second screenshot is mine, I don't have any desktop development option to select. I can only select "Qt Design Studio" and it gives me "no suitable kits found" after installing it.

@xqz5222 You installed Qt Design Studio. But it is not Qt. Check Custom installation in the second screenshot and press next button. Then select the latest Qt to install.
