NoClassDefFoundError with the ?.let{} block in Kotlin

Question

I cannot figure out why I am getting the following error:

E/UncaughtException: java.lang.NoClassDefFoundError: Failed resolution of: Lcom/somecompany/someapp/common/glide/GlideWrapper$loadCircularProfileImg$1$1; at com.somecompany.someapp.common.glide.GlideWrapper.loadCircularProfileImg(GlideWrapper.kt:31) at com.somecompany.someapp.main.MainActivity.showSideBarProfPhoto(MainActivity.kt:179) at com.somecompany.someapp.main.MainActivity.onCreate(MainActivity.kt:115) at android.app.Activity.performCreate(Activity.java:6955) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1126) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2927) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:3045) at android.app.ActivityThread.-wrap14(ActivityThread.java) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1642) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:154) at android.app.ActivityThread.main(ActivityThread.java:6776) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1520) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1410)

with the code:

fun loadCircularProfileImg(ctx: Context, user: User?, targetImageView: ImageView) {

        user?.let {
            // With let getting a NoClassDefFoundError error ????

            GlideApp.with(ctx)
                    .asBitmap()
                    .load(FirebaseStorage.getInstance().reference.child(it.profImgUrl))
                    .into(object : BitmapImageViewTarget(targetImageView) {
                        override fun setResource(resource: Bitmap?) {
                            // Will add code here
                        }
                    })
        }
    }

but not with:

fun loadCircularProfileImg(ctx: Context, user: User?, targetImageView: ImageView) {

    if (user != null) {   // With this the code works

        GlideApp.with(ctx)
                .asBitmap()
                .load(FirebaseStorage.getInstance().reference.child(user.profImgUrl))
                .into(object : BitmapImageViewTarget(targetImageView) {
                    override fun setResource(resource: Bitmap?) {
                        // Will add code here
                    }
                })
    }
}

i used the above code and it working perfect without any error. — Google

when you call loadCircularProfileImg that time user class are define i am call same method and not getting any error like below...

        loadCircularProfileImg(this,User(),imageview)

i am used above code and not getting any error.
