We have a watchOS app in TestFlight that is currently crashing on any device running watchOS 11 and up.
I have an older Apple Watch SE that's capped at 10.6.1 that can run the app just fine, but the same exact install on a newer device fails.
This started happening after I updated my MacBook to macOS Sequoia and Xcode to 16.
In order to get the Watch app to run on the 10.6.1 device, I had to change the Swift Optimization Level from -O to -Osize. I already filed Feedback on this (FB15691116).
I've tried so many different things and have come up with nothing to show for it.
When I look in the IPS file, I see that the crash point in my code on the watchOS 11 device is at

But, as I said, this exact app runs just fine on an older watchOS 10.6.1 device.
Has anyone else encountered something like this, or have any ideas on stuff to try?
