Android Studio 3.1 Instant Run not working

Question

When I updated to Android Studio 3.1, Instant Run features (hot swap, warm swap) stopped working.
Every time when I click on Apply Changes (Instant Run Flash option), Android Studio is restarting my app (even for small UI changes) for every OS above lollipop. (On physical device as well as emulator)

My Instant Run Setting -

Message that I get from Android Studio -

I tried -

Restarting laptop after Android Studio update.
Invalidating cache and restart
Closing the project and import it again

Nothing worked for me. Please help me with this and kindly let me know any more information is needed from my side.

UPDATE:-

My Top level Gradle code -

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.0'
        classpath 'com.google.gms:google-services:3.2.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }
        mavenCentral()
        maven { url 'https://maven.google.com' }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

In my File > Project Structure > Project menu, it is showing my Gradle Version as 4.4 and Android Plugin Version as 3.1.0.

@TimCastelijns Should I disable and re enable the Instant Run? or is there any issue with Instant Run so stop using it? I tried disabling and re enabling it, still the same issue. — Varad Mondkar, Apr 06 '18 at 10:57
there are many issues. Just disable it and don't think about it anymore — Tim, Apr 06 '18 at 11:49

If you are using old version version of gradle. Please upgrade to 4.x

dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'
    }

Update the version and then try.

My current version after AS update is `3.1.0`, Should I downgrade it to `3.0.0` or upgrade to `4.1`? – Varad Mondkar Apr 06 '18 at 10:39

upgrade to 4 then try. I faced the same and this worked in my case. You can also check. – Däñish Shärmà Apr 06 '18 at 10:41
Giving me error `Could not find com.android.tools.build:gradle:4.0.0` – Varad Mondkar Apr 06 '18 at 10:54
Add class path dependencies as **classpath 'com.android.tools.build:gradle:3.0.1** – Nitin Karande Apr 06 '18 at 10:58
i am talking about gradle version not plugin version. Please refer this link: https://developer.android.com/studio/releases/gradle-plugin.html – Däñish Shärmà Apr 06 '18 at 11:07
@DäñishShärmà my Gradle Version is `4.4` and Android Plugin Version is `3.1.0`. I have seen it in `File > Project Structure > Project menu`. – Varad Mondkar Apr 06 '18 at 11:33
