Application becomes unresponsive as soon as i use the buttons

This is a short example that demonstrates the problem.

import sys
from PySide6.QtWidgets import QApplication, QVBoxLayout, QScrollArea, QWidget


class CategoryWindow(QWidget):
    def __init__(self, parent=None):
        super().__init__(parent)
        layout = QVBoxLayout(self)
        scroll_area = QScrollArea()
        scroll_contents = QWidget(scroll_area)
        scroll_contents.setLayout(layout)
        scroll_area.setWidget(scroll_contents)
        layout.addWidget(scroll_area)


if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = CategoryWindow()
    window.show()
    sys.exit(app.exec())

And here is the same code with a tiny change that results in the window being drawn.

import sys
from PySide6.QtWidgets import QApplication, QVBoxLayout, QScrollArea, QWidget


class CategoryWindow(QWidget):
    def __init__(self, parent=None):
        super().__init__(parent)
        layout = QVBoxLayout(self)
        scroll_area = QScrollArea()
        scroll_contents = QWidget(scroll_area)
        # scroll_contents.setLayout(layout)
        scroll_area.setWidget(scroll_contents)
        layout.addWidget(scroll_area)


if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = CategoryWindow()
    window.show()
    sys.exit(app.exec())
