Answer 1

Have you added the below code in your build.gradle(:app) file?

buildFeatures{
        viewBinding true
    }

If not, Just add these above lines before buildTypes like below

    buildFeatures{
        viewBinding true
    }

    buildTypes {
        release {
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

If the problem is the same, Just go to Build>Clean Project. Works fine. Let me know if the problem is not solved.
