I have no idea what's wrong with your Gradle.
Open your your /android folder with Android Studio and look for warnings.
in android/build.gradle, change this line to 7.2.2 and follow any instructions (eg: [Sync now]).
+ classpath 'com.android.tools.build:gradle:7.2.2'
          
Thanks a lot Greg! I appreciate your help!!

 Just in case it's relevant, I encountered this error as soon as I
 installed the Gradle for Java extension for VSCode. As soon as I remove the
 extension, it goes away. The plugin works fine with the extension installed
 and the error messasge present.
