[Python] How do you change the position (column and row) of a PyQt QWidget inside a...

I want to move a QWidget from one position to another. I tried the following:

import sys
from PySide6.QtWidgets import (
QApplication, QMainWindow, QTableWidget, QLabel, QPushButton, QVBoxLayout, QWidget
)


class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.table = QTableWidget(5, 2) # 5 rows, 2 columns
self.table.setHorizontalHeaderLabels(["Column 1", "Column 2"])

# Add a QLabel to cell (4, 0)
label = QLabel("Test")
self.table.setCellWidget(4, 0, label)

# Add a button to trigger the move
self.button = QPushButton("Move widget")
self.button.clicked.connect(self.move_widget)

layout = QVBoxLayout()
layout.addWidget(self.table)
layout.addWidget(self.button)

container = QWidget()
container.setLayout(layout)
self.setCentralWidget(container)

def move_widget(self):
"""Move the widget from cell (4,0) to (3,0)."""
widget = self.table.cellWidget(4, 0)

self.table.removeCellWidget(4, 0)
self.table.setCellWidget(3, 0, widget)
widget.show()

# Debug: Verify the move
print(f"Cell (3,0) now has: {self.table.cellWidget(3, 0)}")
print(f"Cell (4,0) now has: {self.table.cellWidget(4, 0)}")


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


This has the following output:

Cell (3,0) now has: <PySide6.QtWidgets.QLabel(0x26d65f7fc00) at 0x0000026D67071380>
Cell (4,0) now has: None

Process finished with exit code -1073741819 (0xC0000005)


It seems to me that upon rendering, the QLabel is removed. Is there any way to prevent this from happening?
