React Native windows Release build stuck after "Done copying assets"

Problem Description

React Native windows Release build stuck at "Done copying assets"

When a new React Native Windows project is created and the release build is run, it gets stuck at "Done copying assets" and does not proceed further.

This only happens on the first release build. Subsequent release builds work fine.

This is creating a problem for CI/CD pipelines where release build is stuck as it is the first build every time a new build is triggered.

When running locally, when the build gets stuck at Done copying assets, terminating the build (Ctrl+C) and running the release build again works fine.

Here are my full build logs:
build.log

Steps To Reproduce

1. npx --yes @react-native-community/cli@next init myapp --version "latest"
2. cd myapp
3. yarn add react-native-windows@latest
4. npx react-native init-windows --overwrite --logging --template cpp-app
5. npx react-native run-windows --arch x64 --release --logging

Build hangs when running the above steps:

Expected Results

The app builds successfully the first time.

Reproduce with the listed init-windows and npx react-native run-windows --arch x64 --release --logging commands, then compare the first-build output with the attached build.log. Start at the build path around the "Done copying assets" entry and determine why the first Release build stops there. Done means a newly created project completes its first Release build without requiring a second run.
