Mac App Store url problem on Mac M1

once the App Store app for review is opened, my iOS app crashes :(

Weird.

Does that generate a crash report? If so, please post a copy here. See Posting a Crash Report for advice on how to do that.

Here it is:

Hmmm, that crash report has not come across cleanly for reasons I don’t understand. Can you send me a copy of the original .ips file via email? My address is in my signature.

Make sure to reference this thread ’cause I get a lot of email |-:

Hi !

I've exactly the same problem with my app on macOS (M1): app crashes when opening Mac AppStore URL: UIApplication.shared.open(url, options: options)

Here is the trace :

Any clue about it ?

Thanks for your help

I need a complete Apple crash crash report to offer any meaningful advice here. Please post it, using the instructions Posting a Crash Report (hopefully it’ll come through cleanly this time).

Hello Quinn !

I've just sent you the .IPS file via email as you've asked a few messages before mine.

Thanks for your help

Have a good day

Thanks for the crash report. The copy you sent me did what I needed it to do.

The immediate cause of this crash is a trap within UIKit on Mac — as used by both iOS Apps on Mac and Mac Catalyst — because it’s expecting to be called on the main thread but has found itself called on a secondary thread. However, looking through the backtrace I can’t see any indicating that your code is causing this problem. Rather, it seems to have happened as the result of Apple code.

Also, it seems that it’s not just your app being affected by this.

Given that above, I think this is a bug in the OS itself and I recommend that you file it as such.

Please post your bug number, just for the record.

Thanks a lot for your help Quinn Just opened a bug report with bug number: FB10293101 Have a nice day Jeremie

Thank you guys!

I temporarily fixed it using this URL:

"itms-apps://apple.com/app/id*********?action=write-review"

Seeing this crash too. I believe it's been around since the first release of M1 Macs. Confirming also that workaround of using "itms-apps://apple.com/app/id*****" works.
