I had a similar problem. My case is resolved by adding the following lines on app/build.gradle:

implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation('com.android.support:appcompat-v7:28.0.0') {
    force = true
}

Note the force = true part.

Solution 3:^[3]

in build.gradle, just change:

androidx.constraintlayout:constraintlayout:2.1.3

androidx.constraintlayout:constraintlayout:2.0.4

Did you sync your project,I see that yellow message in gradle file if you didn't sync project it wouldn't work
