iPhone 11 on iOS 13.2 crashing

Hi, iPhone 11 13.2 still crash and crash during playing music.

Hi @tsw,

So we can better assist you, please provide a brief description of your current setup using this link as a guide.

Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.

How often does the crash occur? Is there any change after reinstalling or rebooting?

Hi @Dylan, I’m running Core on Windows 10, iPhone 11 13.2 as remote, Wi-Fi streaming, using AirPods Pro. First I found it just stop play music suddenly and I go to the app to check it what happened, when I open the app, it may just crash.

After 2 days testing, the crash seems come with the Bluetooth(when I using AirPods, crash more frequently).

The crash totally random, no any change after reboot and reinstalling.

Hi @tsw,

Can you note the exact local time + date when you observe the next crash? E.g. 12:01PM on 11/4/19?
I would like to see if diagnostics perhaps holds any additional clues regarding this behavior.

hi @noris, I could not provide the exact time, I can only find one crash report in iOS(below), but it actually crashes a lot.

I will record the crash time if it happened.

Hi @tsw,

Thanks for posting that crash snippet, I will inquire with the technical team to see if provides further clues. If you experience another crash, please note the exact local time and date so that we can start looking for any patterns.

Hi @tsw,

We are still looking into the trace you posted, but I would like to gather some more information regarding your report:

  1. Can you confirm how you gathered the above diagnostics log? Did you use XCode to capture the crash?

  2. Can you please open your Roon App on the affected device and let it sit for a minute or two? I have enabled diagnostics mode for the iPhone and what this action does is automatically upload a set of the Roon Mobile logs from the device to our servers.

  3. Can you provide more information regarding your network setup? What is the model/manufacturer of all your networking gear (including router, access points, switches, ect.)

Thanks!

Hi @tsw,

I spoke to our technical team regarding this behavior further and they have noted that iOS 13.2.2 was released today, which includes a change to apps running in the background:
