Hi @rymesaint
Thanks for filing the issue
Instead of cleaning an existing project or creating an ios folder, can you please try to reproduce the issue using a new project without using third-party packages?
flutter create myappcd myapp(add your team id to run the app on physical device)flutter run -v > run.log(this will copy your logs in a file, please drop this file in the comments below)Thank you

Hi @rymesaint
I just tried a physical device with
iOS 14.7.1and it runs fine when running new or existing project on the lateststableandmasterchannelsLogs
run.log
flutter doctor -v
Your issue looks similar to #67222
MateusHBR commentedon Aug 18, 2021
here is happening the same...
all members of my team too.
MateusHBR commentedon Aug 18, 2021
A workaround that worked here is running on the xcode but you do not have the power of hot reload.
rymesaint commentedon Aug 18, 2021
deleting flutter_tools.stamp did not work, using new download from flutter.dev its work only using xcode with terminal still the same error
in xcode debugger output

Hi @rymesaint
I just tried again, I still can't reproduce on a smaller app, when loading Flutter Gallery, which is much bigger, still doesn't get stuck, and only a blank page for a short time which has been there before
On stable channel
RPReplay_Final1629297653.mov
On master channel
RPReplay_Final1629299247.MP4
Does something happens if you wait few seconds on the blank screen? App closes or stays as it is?

I am having the same issue on iPhone with iOS 14.7.1. I just created a new empty project and tried to run it from Xcode, and a white screen appears on the device and stays there forever. This is the log on Xcode's terminal:
From VSCode, running
flutter run, I get the following output:Although it says
Installing and launching, it just keeps on the white screen. It works normally on Simulator with iOS 14.5.My flutter doctor:
15 remaining items

I'm able to reproduce this by downgrading from any other channel to stable.
On stable 2.2.3 downloaded from the website
bin/cache/artifacts/engine/ios/Flutter.xcframeworkcontains:However, when you downgrade from any other channel to stable it instead contains:
It contains the newer
ios-arm64_x86_64-simulatorfrom #85642 in 2.4.0-4.0.pre, and it contains the newer Xcode 12 styleios-arm64_armv7https://github.com/flutter/infra/pull/473.Sure enough I can see the Flutter.framework Info.plist
FlutterEnginebeing embedded in the app does not match the engine hash from stable 2.2.3. And when Irm -rf bin/cache/artifacts/engine/ios*and thenflutter cleanit doesn't reproduce.Another version of old cache files not being cleaned up.

Duplicate of #85062. The stale artifacts problem was fixed by #85075 available on 2.4.0-0.0.pre.

Closing as duplicate of #85062. The workaround is to stay on the beta channel until the next stable, or to run the following after switching to 2.2.3:
