QGC source code run error

Hello,
I am trying to learn about qgc development.
Followed the guide to set the build enviroment on my win10 pc in wsl ubuntu.
Installed Qt 6.6.3 and components needed.
Run sudo bash ./qgroundcontrol/tools/setup/install-dependencies-debian.sh for ubuntu
Launch Qt Creator, select Open Project and select the CMakeLists.txt file.
Ubuntu Desktop Qt 6.6.3 GCC 64bit

After this I builded in QT and run but after running, shell gives me qgc.qtlocationplugin.qgeomapreplyqgc: 1 “Network Not Available” with a empty white screen
Working on it for 2 days but I couldn’t find a solution.
Waiting for your suggestions thanks.

So I downloaded Qt 5.15 on windows and it worked I could build and run QGC. The dev guide site says install only qt6.6.3 but while setup build enviroement asks for qt 5.15.

I was using it without problem for 3 days but I came across a new problem.
While building without editing the code Qt gives this error

:-1: error: dependent ‘\wsl.localhost\Ubuntu\home**\qgroundcontrol\src\QtLocationPlugin\QGCMapEngine.cpp’ does not exist.

QGCMapEngine file is in the directory but it can’t find it.
I deleted respository, downloaded again
Deleted submodules and downloaded again but still get the same error
