FB25121333 created. Though the crash does not happen anymore on iOS 27.0.1. I am hesitant to remove the nonisolated WindowGroup builder workaround yet.

Hi Travis, I tried to reproduce this using a sample project but failed to do so. I filed a report though FB25121333. Although the crash does not happen anymore on iOS 27.0.1, I am hesitant to remove my workaround with the nonisolated WindowGroup creation already.
