      Ugrade to a recent Qt version or apply this fix: https://code.qt.io/cgit/qt/qtbase.git/commit/src/corelib/text/qanystringview.h?id=813a928c7c3cf98670b6043149880ed5c955efb9

      If you do not want to upgrade you should take a look at https://bugreports.qt.io/browse/QTBUG-89977 - there are other fixes for gcc11
