MouseArea does not fire release or clicked event

I have a very rarely issue with the QtQuick MouseArea. In some cases the signals release or clicked are not fired. Howevery, the pressed signal is fired every time. The Project has been migrated from Qt5.15 to Qt6.5.6 and the QML code imports QtQuick 2.12. Maybe this could be the reason, I don't know. Because of the rarely reproducibility it is hard for me to find out a common cause. I hope somebody could help, maybe with a workarround as first step.

Maybe QTBUG-135857 is related to this issue.
