I too had the same issue, I fixed the issue by changing the Gradle(app) compileSdkVersion from 30 to 29 and targetSdkVersion from 30 to 29.

Issue Fixed

@UttamPanchasara Thanks for your response.

This issue getting due to Android Version 10.

Now fixed.

I have added the below line in manifest under the application tag.

android:requestLegacyExternalStorage="true"

Thanks.
