    Description

      Issue:

      When invoking QMessageBox.information in main thread it blocks execution of worker thread until message box is closed.

      This both occurs when using PySide2 5.15.2 and PySide6 6.3.1 .

       

      Expected behavior:

      Invoking QMessageBox.information doesn't affect worker thread.

       

      Notes:

      This doesn't happen when using PyQt5 5.15.7 .
