Controlled multiline TextInput crashes with access violation (0xc0000005)

[ericfle]

Problem Description

A conditionally-rendered controlled multiline TextInput crashes the app with an access violation. The crash is triggered by DrawBlock::~DrawBlock calling DrawText(), which re-enters msftedit and calls ConvertLocalToScreen on an invalid ReactNativeIsland weak reference.

The crash can manifest at different lifecycle points depending on the app's complexity and timing:

• In a minimal app, it crashes on mount (the ReactNativeIsland isn't fully set up yet)
• In a larger app, mount may succeed but the crash occurs when unmounting a focused multiline TextInput (the island's weak ref is already freed during teardown)

          → m_wkRootView.get() → invalid IWeakReference → CRASH

Steps To Reproduce

Minimal Repro

import React, {useState} from 'react';
import {View, Text, Pressable} from 'react-native';
import {TextInput} from 'react-native-windows';

function App() {
  const [show, setShow] = useState(false);
  const [text, setText] = useState('');

  return (
    <View style={{flex: 1, padding: 20}}>
      <Pressable onPress={() => setShow(!show)}>
        <Text>{show ? 'Close' : 'Open'}</Text>
      </Pressable>
      {show && (
        <TextInput
          value={text}
          onChangeText={setText}
          multiline
          style={{borderWidth: 1, minHeight: 60}}
        />
      )}
    </View>
  );
}

export default App;

Steps: Click "Open" → app crashes.

What works (no crash)

• Removing multiline — single-line controlled TextInput works fine
• Removing value/onChangeText — uncontrolled multiline TextInput works fine
