Android Studio 3.6.1 with Gradle Plugin Version 3.6.1 and Gradle Version 5.6.4 not working

My application is working very well. I have just updated Android Studio 3.6.1,

After updating Android Studio I got this dialog and I am going to update the version of the Gradle Plugin as below.

After updating, My application getting crashed and getting the following errors.

There is only one solution which I have tried is reverting back the version of Gradle which I have updated but what if I want to use the latest versions.

Update:

One of my projects is working with some version of Android Studio and Gradle. Here is Firebase SDK is different in both project so I am thinking that Firebase is Project.

Any help? What should I do?

buildToolsVersion "29.0.2"

remove this line from build.gradle
