Access violation when exiting while a project is being loaded

When opening a sufficiently large CMake project so the loading is not instantaneous, and closing QtCreator while it is loading it (CMake has not finished its configure and generate steps), it crashes at exit in ProjectExplorer4!ProjectExplorer::TreeScanner::release.

Sadly the crash is not systematic.

FAULTING_SOURCE_LINE: D:\Qt\5.13.2\msvc2017_64\include\QtCore\qlist.h
FAULTING_SOURCE_FILE: D:\Qt\5.13.2\msvc2017_64\include\QtCore\qlist.h
FAULTING_SOURCE_LINE_NUMBER: 826
FAULTING_SOURCE_CODE:
  824: template <typename T>
  825: Q_OUTOFLINE_TEMPLATE QList<T>::QList(const QList<T> &l)
> 826: : QListSpecialMethods<T>(l), d(l.d)
  827: {
  828: if (!d->ref.ref()) {
  829: p.detach(d->alloc);
  830:
  831: QT_TRY {

If a just in time debugger is configured, it will be opened.

I've attached details about the crash in qt-creator-faad83d5a37448b472af2efa76b7193c83f2c1f1-msvc2019-x86_64-windows-qt-5.13.2-msvc2017_64.txt (like all threads stacktrace dump).
