Same issue, it seems that in this code (DownloadWorker.kt)

                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q && saveInPublicStorage) {
                    val uri = createFileInPublicDownloadsDir(actualFilename, contentType)
                    savedFilePath = getMediaStoreEntryPathApi29(uri!!)
                    outputStream = context.contentResolver.openOutputStream(uri, "w")
                } else {
                    val file = createFileInAppSpecificDir(actualFilename!!, savedDir)
                    savedFilePath = file!!.path
                    outputStream = FileOutputStream(file, false)
                }

uri or file var is null (depend on which Android version we have)

Did someone solved this issue? any fix?

You can add a try catch block here. I added it and my issue was resolved. In my case, a file with same name was already present on the location of my downloading file, and that's why it was failing. By adding a try catch, at least the code will not break.
