Describe the bug

Traceback (most recent call last):

    MainWindow.setSizePolicy(sizePolicy)

Additional context

The error you're encountering seems to be related to a mismatch in the arguments passed to the setSizePolicy function in a PySide2 application. The error message indicates that the function is expecting different argument types than what is being passed.

It seems like you're trying to set the size policy for a MainWindow, but the arguments passed to setSizePolicy are not in the expected format. The setSizePolicy function can take different argument types based on its overloads.

Here's an example of how you might set the size policy for a MainWindow in PySide2:

Copy code
from PySide2.QtWidgets import QMainWindow, QApplication, QSizePolicy

class MyMainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        # Create a size policy
        sizePolicy = QSizePolicy(QSizePolicy.MinimumExpanding, QSizePolicy.MinimumExpanding)
        
        # Set the size policy for the main window
        self.setSizePolicy(sizePolicy)

if __name__ == "__main__":
    app = QApplication([])
    mainWindow = MyMainWindow()
    mainWindow.show()
    app.exec_()

In your specific case, it appears that the code is trying to set the size policy within the setupUi method of the MainWindow. Ensure that you are passing the correct argument types when setting the size policy within this method.

Check the version compatibility of your code with the PySide2 library and make sure it's in line with the expected argument types for the setSizePolicy function. Upgrading or downgrading PySide2 might resolve compatibility issues if the error persists.

This happens when both PyQt5 and PySide2 dependencies are installed. Remove one of them (it can be done directly via pip) and the application should work.

I can confirm the mentioned workaround

env QT_API=pyside2 guiscrcpy

fixes the issue here (also on Arch)
