Cannot fit requested classes in a single dex file after updating android studio

My project was compiling fine before updating the android studio. But after i updated android studio to v3.5 i can't compile my project. I am getting following error:

Cannot fit requested classes in a single dex file (# methods: 72945 > 65536)

I can't even change a single line code.

My gradle:

apply plugin: 'com.android.application'

I researched on stackoverflow for dex file errors, some people says "enabling instant run resolved the issue for me" I suspected about instant run because they have changed the instant run mechanism and removed instant run settings from android studio. Maybe this is the problem?

How can i resolve this problem without enabling multiDex support?
