I just updated my eas & expo cli’s while already on SDK 46. I used to be able to press R key to reload the app while focus in the simulator. It seems this is no longer working. Any ideas?
I can still press R on the terminal

I go to start emulator on my mac m1 and it'll bring up the phone emulator however my project is not uploaded to the phone.
I am getting this error in the terminal:
› Opening on Android...
› Opening emulator Pixel_5_API_33

This download is taking longer than expected. You can also try downloading the clients from the website at https://expo.dev/tools

The ios emulator seems to be working fine
I just solved this issue for myself, it appears your emulator doesn't have enough storage assigned to it.
Here's how you can increase the storage on your emulator
For my emulator I increased the device Internal Storage to 8GB and enabled No SDCard. This has allowed me to emulate my expo react-native app on Android while running on my M1 silicon chip MacBook.
I haven't used React Native or Expo since 2019. I've tried creating an Expo app with npx create-react-native-app and expo init and neither project prints out a QR code. Opening the Metro bundler URL used to open a webpage that also displayed the QR code, but the Metro URL in the output now returns a JSON response.
Developer tools running on http://localhost:19002

Is this still a development feature with Expo?
I misinterpreted the Linking output to be about launching apps/activities via a URI scheme from the RN app. Metro Bundler now prints out a QR code after I run:
npx uri-scheme add anyarbitrarystring
as mentioned here.
Seems like unnecessary setup for generating a new project and should be something mentioned in the dev setup guide.
However, even on the same network, the new QR code does not do anything in Expo Go on Android.
I have Custom Development Client App build with EAS and it is always crashing when I try to open React Native Debbuger without any log.
Steps to reproduce:
eas build --profile development --platform android
Start Emulator and download build from link produced in step 1. Open the App.
expo start --dev-client
Press a │ open Android
Press m │ toggle menu
Press "Debug Remote JS" on device/emulator
React Native Debugger opens in th browser but app is crashing and does it everytime I try to open it again.
Same thing happens on the physical device.
React Native application might be using a library that uses JSI, e.g React Native Reanimated 2 (https://docs.swmansion.com/react-native-reanimated/docs/#known-problems-and-limitations) or React Native MMKV (https://github.com/mrousavy/react-native-mmkv#limitations).
With these libraries, remote debugging won't execute properly. I'd start on checking of known limitations on your project's 3rd party libs.
I noticed that connecting expo-dev-client via localhost automatically crashes the app.
Try to use LAN network and make sure that your device and computer are on the same network.
I've been working on a react-native app managed mode built on expo, I was working from a mac at first which worked perfectly fine using the IOS simulator it didn't work on android emulator on mac, here i switched to a windows computer and the issue still exists on the android emulator, executing the command "expo start" the app crashes after the splash screen before the logo appears, I tested the app on a real device on the debug mode and it worked! also after deploying the apk file the app works with no issues, the only problem is it's not working on android simulator using expo client, things i tried to solve the issue including trying to reinstall android studio and install the latest version, tried updating expo sdk to latest version also tried playing around with the app.js from where the app launches the first time but still crashes at the same point, it's not showing any errors or warning it just crashes, any suggestion or something i could try would be very helpful thanks.
I am also having a similar issue : after upgrading to the latest release (SDK 41) the android simulator hangs often and the app crash without any errors. But works some time .
I have a problem when running react-native run-ios on my project.
The IOS emulator launch well.
Then the application start (react-native white splash screen) and immediately after that, it return me to the Iphone home screen.
If I Cmd-Shift-H (with pressing H two times) I saw the app in the background (still with the react-native white splash screen).
When I click on it, it return me to the home screen again.
If I launch the Xcode project and run the app, it work fine and I can navigate in my application.
I've had some troubles with my app before, the IOS version was 'abandoned' and I've installed a lot of modules and changed the name of the project in the mean time, before trying to make it work on IOS.
Then I've decided to create a new project with react-native init myNewProject (because I couldn't figured out how to fix the IOS, something with a workspace not configured) and copy paste my old src and index.ios/android.js inside.
So now Android is still working and IOS is only working if I launch the app from Xcode.
I've tried to reset the emulator but it don't change anything.
I don't have any logs about app crash or something.
The Android app version is working fine.
Any idea ?
Logs
I've put the device logs after running react-native run-ios on a gist

Additional Information
React Native version: 0.35
Platform: IOS
Operating System: macOS El capitan
Xcode: Version 8.0
I ran into this problem, and solve it:
In my case i install third-party native component in my project and link it using command react-native link <component-name>. Than i have a problem about you wrote:
Running project by Xcode - works fine. Bundling start, after loading dependency graph.
But runnig project by react-native run-ios app hide immediately and bundling not started after loading dependency graph. And not any errors happened.
I tried reinstall all, clean npm cache, react-native upgrade, delete build folder, delete derived data... nothing helped.
I found one way that helped me:
I remove that problem library not manyally from Xcode, but from terminal using command react-native unlink <component-name>. Its way to resolve this problem for me, maybe for you too.
Sorry for my english.
