Build Android Applications

I cannot build Android applications.
Please let me know how to deal with it so that I can include the details below.

1. Build → Android App Build → Release Build.
2. Enter the alias password.
3. The following error message appears.
　　[Error Message]
　　Build failed.
　　App build failed.There may be a build configuration error.
　　Please reconfirm the settings below:
　　·Is AndroidManifest.xml written correctly?
　　·Is the keystore setting correct?
　　Please correct the settings and try building again.

How did the build go
Due to an update to the app, we carried out the build operation.
As I have uploaded this app to Googleplay in the past
The version has been updated to 2.0.0.

Thank you for your cooperation.
