Android Studio 4.0 file > New > Activity OR Fragment not working

Question

I have android studio 4.0 installed & I am unable to create new activity OR fragment from File > New menu.

All that happens is just a gradle build & files don't show up after I click the Finish button.

Following is the system environment.

Studio Version: 4.0
SDK build tool: 30
Gradle wrapper: 6.1.1
OS: macOS Catalina (10.15.2)
Machine: MacBook Air (2017 

I am using an android navigation UI version: 2.2.2 and also tried to create new activity/fragment from navigation file using New Destination still no result.

Let me know if any other information is required.

Please open your app build.gradle file and delete debug config from signingConfigs and try again:

 signingConfigs {
   // delete this entire debug block 
   debug {
        storeFile file('file path')
        storePassword 'password'
        keyPassword 'password'
        keyAlias = 'password'
    }
}
