c++ - Cannot remove duplicated Android 6.0.0 Clang compilers kits auto-detected in Qt6

Question

Problem 1:

I'm using Windows 10 Home. I have installed Qt6, Android Studio 2019, and Visual Studio 2019. Before installing Visual Studio 2019, Qt6 was working fine, but since I have installed Visual Studio 2019, there are now duplicated compilers in Qt6 for all Android 6.0.0 Clang kits (please see screenshot). Can someone tell me how to removed the duplicated ones? The Remove buttons are all greyed out. Why does Qt6 auto-detect more than one of the same compiler?

The duplicated compilers under Auto-Detect are:

• Android Qt 6.0.0 Clang arm64-v8a
• Android Qt 6.0.0 Clang armeabi-v7a
• Android Qt 6.0.0 Clang x86
• Android Qt 6.0.0 Clang x86_64

Qt6 have auto-detected identical instances three of each, and the remove option for all of them are greyed out.

Problem 2:

Once openned a project example (ie. Coffee machine, the default example project that comes with Qt6 installation), in the General Messages (Alt + 6) of Qt6, it shows the following:

2021-01-12T18:19:28 Clang Code Model: Error: The clangbackend executable "C:QtToolsQtCreatorinclangbackend.exe" could not be started (timeout after 10000ms).

Can someone please explain what is happening and what should I do to correct those errors? I could not find any answers by Googling so far. Has anyone encountered similar problems before?
