I am getting same crash. Could you please check this.

private fun downloadMedia(filePath: String) {
val fetchConfiguration = FetchConfiguration.Builder(this)
.setDownloadConcurrentLimit(5)
.setProgressReportingInterval(500)
.build()
Fetch.Impl.setDefaultInstanceConfiguration(fetchConfiguration)
fetch = Fetch.Impl.getDefaultInstance()
val mediaRequest = url?.let { Request(it, filePath) }
mediaRequest?.let { request->
request.priority = Priority.HIGH
request.networkType = NetworkType.ALL
// fetch = if (fetch == null || fetch?.isClosed == true) FoneAppApplication.instance.getFetch() else fetch
fetch?.enqueue(request, { updatedRequest: Request? ->
Timber.d("Media File enqueue successfully!! ${updatedRequest?.id}")
}) { error: Error? ->
Timber.d("Media File is not enqueue!! ${error?.name}")
}
}

I think it's a serious issue. We are facing the same when we are trying to download back-to-back images.

is there any update?

Once a Fetch instance is closed It can no longer be used. When the activity is started check if fetch is closed by doing the following

 private Fetch fetch;
 
     @Override
    protected void onStart() {
        super.onStart();
        if (fetch == null || fetch.isClosed()) {
            //create new fetch instance
            final FetchConfiguration configuration = new FetchConfiguration.Builder(this).build();
            fetch = Fetch.Impl.getInstance(configuration);
        }
    }
    
        @Override
    protected void onDestroy() {
        super.onDestroy();
        if (fetch != null && !fetch.isClosed()) {
            fetch.close();
        }
        fetch = null;
    }
