Hi everyone!

Anyone else seeing crashes like this: Fatal Exception: NSInvalidArgumentException. -[_UISnapshotWindow actualSceneBounds]: unrecognized selector sent to instance

I'm encountering a crash within 3-4 seconds of launching my iOS app specifically on devices running iOS 14. The crash log indicates an NSInvalidArgumentException with the following message:

Here's what I've observed: The crash consistently occurs within 3-4 seconds of app launch on iOS 14 devices.

I'm seeking assistance with:

Understanding the Cause: Any insights into potential causes of this crash, particularly related to _[_UISnapshotWindow actualSceneBounds] and its interaction with iOS 14, would be greatly appreciated.

Replication Steps: If possible, guidance on how to reliably replicate the crash on a development device would be extremely helpful for debugging purposes.

Solutions: Any suggestions or known workarounds to address this specific crash or similar issues in iOS 14 would be invaluable.
