D8 Error Occurs (During "Compiling Libraries")

I am facing a critical build issue in the builder. The project builds successfully when no additional screens or layouts are added. However, as soon as I add a new screen or even a simple layout (e.g., Vertical Arrangement), the build fails during the “Compiling Libraries” stage with a D8 error.

Error Message:
“Build failed due to an error in the D8 stage, not because of an error in your program.”

Steps to Reproduce:

  1. Create or open an existing project
  2. Ensure the project builds successfully
  3. Add a new screen OR add a simple layout (like Vertical Arrangement)
  4. Try to build the project

Expected Result:
The project should build successfully even after adding new screens or layouts.

Actual Result:
The build fails during the “Compiling Libraries” phase with a D8 error.

Important Notes:

  • The issue occurs even when extensions are working fine initially
  • The same extensions do not cause any error until a new screen/layout is added
  • This suggests a possible issue with how additional resources or libraries are being compiled
  • The problem seems unrelated to blocks or logic

Request:
Please investigate this issue, as it prevents scaling the app (adding screens/layouts). A fix or workaround would be highly appreciated.
