Accidentally changed the source code, please help

[kdrpro1]

When I was learning code, I accidentally clicked on QLabel and qlabel source code folder Qt\6.6.1\mingw_64\include\QtWidgets, in the compiler, and then changed it to my code.
Now my QLabel cannot be used. Can you paste the source code here?
