How can I ignore it? the build was not accepted, not even showing up in TestFlight.

With Xcode 13.2.1, Mac Monterey 12.2, this issue is still unfixed on M1 MBP. So annoying! Had to switch back to Intel Mac Mini quite often. What a waste.

Have you solved this issue? I'm having this issue too. It seems this is associated with the copy paste not working on simulator - I can't paste text into the App, the sim can't open the pasteboard file. Did that happen to yours as well?

Still having this same issue on M1 mac.

Seems Xcode 12.5.1 has largely fixed it. I've been using it for 3 hours it's improved from 15 seconds frozen to 3 seconds frozen post launch.

Not sure if this is exactly the same issue but my App will be unresponsive to mouse click for about 10 seconds after run in simulator. I've tried everything the only one worked was to delete the simulator then add it back. It only worked for maybe half a day then it'll come back unfortunately.

Same question...have you found a solution?

I faced a similar issue after enabled DarkMode - yes we've only enabled it recently. Turned out when the App went to background it was trying to take a snapshot of the top view, which I suspect is required by DarkMode, and will layout the views again, hence calling the NSAttributedString initWithData in my cell constructing method. I could see that this crash happened during App is backgrounded in Crashlytics, even tho it's still on main thread. I could also reproduce it easily once I figured it out. The fix is pretty straightforward: to use a lazy var to init that attributedStr to prevent it from being called again when the App goes to background.
