Error in construction of QApplication before QWidget.

[reneela]

There is a issue about running "phy template-gui params.py" in the phy2 environment that I created. And it returns the error as shown in the screen shot. We had already tried to run the command "pip install PyQtWebEngine" and try launching phy again. But it can't work. Could you pleas help us to solve this problem? Thank you very much.

phy template-gui params.py --debug returns this:
