Kotify not working on RELEASE MODE

[PMARZV]

I was implementing Kotify in an app and everything workedd correctly in debug mode. When i switched to release mode, it does not work. I have a try/catch that tris to do the code and then with an adapter i put it on the app and the catch returns another view in the app. In debug mode everything works correctly and the TRY is triggered. But in release, it triggers the CATCH meaning thatt the code has failed (api call)
CODE TRY CATCH

  lifecycleScope.launch {
        try {

                val kotify = Kotify(
                    clientID = "5ef1e8a612cb4f12b3343ad26427ec93",
                    clientSecret = "6752b38c773741ea8e15404e613bea83"
                )

                val playlist: List<PlaylistPagination.Item> =
                    kotify.playlists.get("37i9dQZEVXbMDoHDwVN2tF").tracks.items


                val tracks: ArrayList<Track> = playlist.map { it.track } as ArrayList<Track>

                for (i in 0 until tracks.count()) {


                    val SEVERALartistsname: ArrayList<Artist> =
                        tracks[i].artists as ArrayList<Artist>
                    for (o in 0 until SEVERALartistsname.count()) {
                        if (artistname == null) {
                            artistname = SEVERALartistsname[o].name
                        } else {
                            artistname = artistname + ", " + SEVERALartistsname[o].name
                        }
                    }


                    val SEVERALalbumimg: ArrayList<Image> =
                        tracks[i].album?.images as ArrayList<Image>
                    val artworkTrack = SEVERALalbumimg[2].url


                    val songname = tracks[i].name ?: "N/A"
                    val nameartist = songname + System.lineSeparator() + artistname


                    courseList2.add(namespoty(i + 1, nameartist, artworkTrack))
                    SEVERALartistsname.clear()
                    artistname = null


                }

            val courseRVAdapter2 = CourseRVAdapter2(courseList2, true)
            courseRV.adapter = courseRVAdapter2

            loadingPB.visibility = View.GONE

        } catch(e:Exception){
            Log.i("HELLO", "CATCH")
            loadingPB.visibility = View.GONE
            Log.i("HELLO", "CATCH2")
            courseList2.add(namespoty(null,"",""))
            val courseRVAdapter2 = CourseRVAdapter2(courseList2, false)
            Log.i("HELLO", "CATCH3")
            courseRV.adapter = courseRVAdapter2
            Log.i("HELLO", "CATCHEND")
        }

it has to do with the relase mode and a thing to mention is that i have the proguard rules activated and i dont now if i have to add a rule excluding and which one! I would help a lot!
Your work is awesome! (take into account that is release mode and i dont have the logcat to see wheres the error so im stuck)
