There can be several reasons why you may face this issue. Here are some solutions that you can try:

1. Make sure you have the correct version of the Activity Result library in your build.gradle file. The latest version is "1.1.0-alpha01".

2. Check if you have added the following lines in your app-level build.gradle file:

   implementation 'androidx.activity:activity-ktx:1.2.2'
   implementation 'androidx.fragment:fragment-ktx:1.3.3'
   

3. Ensure that you have imported the correct namespaces in your Kotlin or Java file:

   import androidx.activity.result.contract.ActivityResultContracts
   import androidx.activity.result.ActivityResult
   

4. Verify whether you are using the correct syntax to invoke and register the activity result:

   private val someActivityResultLauncher = registerForActivityResult(ActivityResultContracts.SomeContract()) { result ->
      // Handle the result
   }
   

5. If you are still facing the issue, try cleaning and rebuilding your project or invalidating cache and restarting Android Studio.

6. You can also try updating Android Studio to the latest version, as it may contain bug fixes.
