It seems that PyQt5 with version 5.14.1 is not compatible with macOS Big Sur (11.1). The howtrader app will experience an ANR with a warning message

Warning: QApplication was created before pyqtgraph was imported; there may be problems (to avoid bugs, call QApplication.setGraphicsSystem("raster") before the QApplication is created).

Problem solved after upgrading to 5.15.2
