qt5 - QtCreator fails on MacOS SDK 11.1

Question

I have Qt5 from brew in: /usr/local/Cellar/qt5/5.15.2/bin/

I use QtCreator 4.12.82.

I have MacOS Big Sur 11.1 with XCode installed in ls /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk.

When I create a new standard project in QtCreator I get the following error:

10:35:16: Running steps for project test2...
10:35:16: Starting: "/usr/local/Cellar/qt/5.15.2/bin/qmake" /Users/joefresna/VideoImageEdit/test2/test2.pro -spec macx-g++ CONFIG+=x86_64 CONFIG+=qtquickcompiler

Error while building/deploying project test2 (kit: Qt 5.15)

(Note that even if I delete the build directory I still get the warning about wiping the directory)

The QtCreator Kit points to the qt installed via brew (indicated above). I tried to change the compilers in QtCreator > Projects > Manage Kits > Kits > Compiler and I tried both GCC and Clang from /usr/bin and from XCode, without success.

When I type xcodebuild -showsdks, I get:

watchOS Simulator SDKs:

Do you know how to solve this problem?

I have found a solution! It is enough to search and delete all occurrences of .qmake.stash. I failed to find them because they can also be outside the build folder! Once the .qmake.stash files have been deleted, the program compiled and run successfully.
