I have the same issue. I was tried Invalidate Cache / Restart
& also sync project with Gradle Files
but still didn't work.
But worked by use the following steps:
upgrading gradle distribution version at gradle.wrapper.properties.
distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-all.zip
And also Android Gradle Plugin at build.gradle project
classpath 'com.android.tools.build:gradle:4.1.2' //upgrade gradle plugin here
Then Invalidate Cache / Restart
That's all solved my problem. Hope you too
