I have the exact same issue:, building for a macos app.
environment:
sdk: '>=3.2.1 <4.0.0'
dependencies:
flutter:
sdk: flutter
provider: ^6.0.3
flutter_bloc: ^8.1.6
cupertino_icons: ^1.0.2
record: ^5.2.0

I can get the list of devices, IsRecording and isEncoderSupported values. But as soon as I await for the path from .stop() I never get the result and the file is never written.

final path = await recorder.stop();
await recorder.dispose(); < --- Never gets executed
debugPrint("Path to file is $path"); < --- Never gets executed

I have used the debugger to step into the code and delve deep into the abyss but it becomes quite scary at some point when dealing with I got to platform_channel.dart..

Any advice or ideas for troubleshooting will be appreciated.

I found a solution to this issue:

Its the fact that MacOs only allows access to certain folders when developing and the sandbox is used. I was writing the file to /tmp/out.m4a but it seems you can only write to specific folders

https://developer.apple.com/documentation/security/accessing-files-from-the-macos-app-sandbox

You can disable the sandbox as per
https://stackoverflow.com/questions/68114273/flutter-for-macos-how-to-access-user-selected-desktop-files-and-folders

Best practice would be to only write to folders your app has access to but for dev purposes disabling the sandbox should be find as long as you remember to fix your app before releasing it into the wild.
