Hello, I'm seeing a issue on a Kotlin multiplatform iOS project where the app becomes 'frozen' sometimes when it is resumed (i.e. send the app to background, use some other apps, then resume the app some time later). Eventually the system kills it or I have to kill it. It happens for many of my users in production as well.

I extracted the ipa crashfile from the device and I'm seeing EXC_CRASH, SIGKILL with reason "failed to terminate gracefully after 5.0s". There's no other crash generated by the app. It's not a 100% repro.

The issue doesn't occur on Kotlin 1.7.21, but occurs on 1.8+ including on the new 1.9. Have there been any changes that might cause this issue or any thoughts on how I can go about debugging this issue? Comment out line by line? For now I've had to downgrade back to Kotlin 1.7.21
