I recently had to migrate to use embedding v2 for my flutter app. I can run my app on the emulator and it works fine, but when I try to run it on a real device (Android) it crashes immediately. The screen flashes up with the white background, but immediately crashes, so it's literally just a flash of the white screen. I'm absolutely lost on how to fix it. Happy to share any parts of the code if there is something you think might need looking at.
I am assuming the issue is to do with the migration to embedding v2 as I've only made minor changes elsewhere since the last app version.
Or if anyone has any tips on how I might go about debugging this? I have a real device attached, but no errors occur. It just shows installing on the IDE, but the app crashes on the phone.
EDIT: After a Flutter Clean and running the app on a real device again. I get the following:
E/AndroidRuntime(13098): FATAL EXCEPTION: pool-3-thread-1

And this is my manifest:
