Hey there! I’ve dealt with this exact aapt2 missing error before when working on Android projects, so let’s walk through how to fix it step by step:

• Verify Build Tools Installation
  Open Android Studio’s SDK Manager (go to Tools > SDK Manager from the top toolbar), switch to the SDK Tools tab. Look for Android SDK Build-Tools 27.0.3—check if it’s installed. If not, tick the box and click "Apply" to install it. If it’s already there, try uninstalling and reinstalling it—sometimes the installation can get corrupted or skip files.

• Check the File Path Manually
  Open your file explorer and navigate to C:\Users\Awaisi3\AppData\Local\Android\Sdk\build-tools\27.0.3\. Double-check if aapt2.exe exists in this folder. If it’s truly missing, the reinstall step above should fix it.

• Update Android Studio & Gradle Plugin
  Outdated Gradle plugins or Android Studio versions can cause compatibility issues with Build Tools. Try updating your project’s Gradle plugin version in the root build.gradle file (modify the line classpath 'com.android.tools.build:gradle:x.x.x' to a stable version matching your Android Studio), and also update the Gradle wrapper version to match.

• Clean & Rebuild Your Project
  After any of the steps above, go to Build > Clean Project and then Build > Rebuild Project. This clears any cached build files and forces the project to generate everything fresh, which often resolves missing file issues.

If none of these work, you could manually download the Build Tools 27.0.3 zip from the official SDK repository and extract it into your build-tools directory, but the steps above should cover most cases.
