When user opened my application, it crashed immediately. [Firebase crash report CFNetwork]

When user opened my application, it crashed immediately. This is crash log message from firebase.

com.apple.CFNetwork.Connection 
EXC_BAD_ACCESS KERN_INVALID_ADDRESS

After restarting iPhone, user can use my application without crash. I cannot reproduce this crash from other device.

Here are .ips crash log that I changed to .txt.

Do you have any idea to fix this?
