I can build it and run (the window appears) so I'm happy :) but the errors are strange
Possible fix?

The errors occur because the Ui::MainWindow class is only generated during build-time.

After you have built the project at least once, the errors will disappear (restart Qt Creator if they don't)

Hi @cookie1234, and welcome!

What happens when you select a different kit?

Anyway, please share a screenshot of "Edit" > "Preferences..." > "Kits" > "Kits"

The problem occure with different kit too.

So I guess I need to configure the Cmake Tool, how to do that?

CMake is not your main issue.

Your kits all look strange -- the Qt version numbers are missing. Notice also that your screenshot says "the kit has no valid Qt version".

What does "Edit" > "Preferences..." > "Kits" > "Qt Versions" look like?

Yeah, it does.

Click on the MinGW 64-bit one; do you see any clues?

Open the Windows Command Prompt and run C:\Qt\5.15.2\mingw81_64\bin\qmake.exe -query

What do you see?
