Can't seem to get a window from PYQT5 in Pycharm (macOS Big Sur)

Question

I am using macOS Big Sur beta currently. I have been able to download the libraries via Pycharm 2020.1.2 however, when running my program, no window appears to show what I've been working on.

Example:

Here is a simple line of code I've gotten as an example.

import sys
from PyQt5.QtWidgets import QApplication, QLabel

app = QApplication([])
label = QLabel('Welcome to PYQT5 Tester')
label.show()
app.exec_()

When I run the app, there are no errors and the sole description is my file directory. I am really confused to if I haven't installed anything but any help would be appreciated.

下降到 PyQt5==5.13，它现在对我有用。
