Research direction
Start with electrum/plugins/trezor/qt.py at pin_dialog line 150 and trezorlib/qt/pinmatrix.py at get_value line 120, then trace when the QLineEdit is destroyed. Reproduce the Trezor PIN-dialog crash if possible and identify the lifecycle condition that triggers it. Done means the reported deleted-QLineEdit RuntimeError no longer occurs during PIN entry.
