dda67753250c57c85b3f005aa27c28117555aadd (qt-creator/qt-creator/4.14)
Description
Steps to reproduce:
1. Run Creator from 4.14 branch compiled against Qt 5.15
2. Load a Creator project from 4.14 branch compiled against Qt 6
3. Start debugger
4. When a new Creator appears, load there the same project again (Creator project from 4.14 branch compiled against Qt 6)
5. Start debugger there. When launching the 3-rd Creator you get the following crash (seen in the first Creator, compiled against Qt 5.15):
