Type org.opencv.calib3d.Calib3d is defined multiple times (but only on release, not debug)

In my Android application, I have both imported the OpenCV library, as well as integrated a live edge detection library, which in turn uses OpenCV on its own.
Originally, this created a conflict between the two versions of OpenCV, but I was able to resolve that.
I am now trying to do a production release for the first time since this change, and I am encountering the following error during my release build (in the mergeDex...Release stage):
Type org.opencv.calib3d.Calib3d is defined multiple times: .../OpenCVSDK/build/.transforms/73aaad4d2991f9ad7ec3aa9b43023dc9/transformed/release/org/opencv/calib3d/Calib3d.dex, .../app/build/intermediates/external_libs_dex/prodSbirRelease/mergeExtDexProdSbirRelease/classes3.dex
Why is this suddenly an issue now, with a release build, when it was (and continues to be) fine with debug builds? And how can I fix it?

Not sure what is wrong.
Any help will be appreciated.

Solved!.
Implemented multidex from the developer site.
https://developer.android.com/studio/build/multidex
Also there were two view model classes CameraXViewModel & CameraXviewModel.kt, removed the file CameraXviewModel.kt from the project. CameraXViewModel is the one which is used and CameraXviewModel was not referenced any where in the project.
ASFAIK Java and Kotlin is case sensitive for classes, so ideally it should work. Here everything compiled and APK generated but app crashed at runtime.
Hope this helps someone.

If you have it declared as follows in project build.gradle
maven { url "https://jitpack.io" }
try changing to
maven { url "https://www.jitpack.io" }

You must check your internet connection and disabled gradle offline mode in setting
after that do :
File > Invalidate Cache and restart.
And try to sync the app !

Why does adding product flavors to my libraries build.gradle file cause my local app to be unable to resolve imported dependencies from said library?

I'm developing an android application for my company. The project holds directories: our sdk (library in this case) and a sample app that imports the sdk. When I add product flavors to the sdk (library) the app breaks due to being unable to resolve the dependencies imported from the sdk.
The errors are:
error cannot find symbol class S
error cannot find symbol class SO
error package S does not exist
error method does not override or
implement a method from a supertype

I have been trying to fix this for 4 days and am still stuck. I've tried all of the typical solutions found on stackoverflow. This has been a cascade of problem after problem and this specific one came directly after updating how the sdk is loaded in the app's build.gradle file. I suspect something is wrong with this line where I import the sdk as a dependency (end of app's build.gradle):
implementation project(path: ':*******-sdk', configuration:'default')
but not including 'configuration: 'default'' causes another bug where the app cannot discern which buildVariant of the SDK to use.
How can I get my app up and running while also maintaining the product flavors found in the SDK?

Caused by: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives:

I am not able to build release APK. Every time I get DexMergerException.
Here are my build.gradles:
I am using MVVM structure. I have core(package name for core is same as my app package) has my lib where I only write view models, models and network layers.

I tried so many time and I am not able to understand the reason behind this issue.

Same happened today to me and this is what solved the issue:
Find all the dependencies of com.google.android.gms:play-services.
They all have now different versions. Just place the mouse over them and correct the version numbers (i.e. for me was upgrading maps from 15.0.0 to 15.0.2 and tag-manager to 15.0.1)
