Please provide the following:

  1. SDK Version: 41
  2. Platforms(Android/iOS/web/all): iOS
  3. Add the appropriate “Tag” based on what Expo library you have a question on.

With bare workflow (ejected from managed) I can build and publish my app for iOS, and all works great in both simulator as well as via TestFlight in the phone. However if I do expo publish for my “beta-1” release channel, even without changing anything else than just version number in app.json then the app crashes immediately on the startup after it has loaded the update.

The only error msg I can see in syslog is

May  8 19:57:58 MBP-2020 syslogd[58961]: ASL Sender Statistics
May  8 19:57:58 MBP-2020 app[19933]: assertion failed: 20E241 18E182: libxpc.dylib + 50305 [454053CA-B690-3B99-BE31-2369B04EA493]: 0x7d

I created my app as managed in SDK40, upgraded to SDK41 and then ejected. I have checked expo-updates config against the bare expo template created with expo init and all looks good.

Any tips on what to try to do to either fix or at least get better logs on the problem so that can post issue to Expo Github?

Did you manage to solve it?
Can you please share how?

@cyberserve No I did not solve it. I have been occupied with some other work, but should be able to re-test this on the weekend and then submit an error report in Expo Github to get hopefully help in at least debugging this properly.
