Error when running qmldom example (qmldomloadeditwrite)

Steps

1. download the correspond sources to build and run qmldom example
   1. with file1.qml
2. build and run qt6\qtdeclarative\examples\qml\qmldom

Current result

• qmldom example doesn't create editedfile1.qml

qt.qmldom.writeOut: failure reformatting  "C:/Users/[UserName]/AppData/Local/Temp/editedfile1.qml"
"Error while writing" 

Expected result

• editedfile1.qml is properly created and its code should be different from file1.qml

I am suspecting the code in the function writeOutForFile in qqmldomitem.cpp

When I commented out the condition in the code, editedfile1.qml is created in the folder.

editedfile1.qml
