AlertBridge is not a class of mine. Strangely, the stack trace reported by Crashlytics does not have any of my code. Here is the complete stack trace. Again, none of the classes seen in the stack trace are mine. 0	SwiftUI												0x1c9bf3ae8 AlertBridge.preferencesDidChange(_:) + 2604 1	SwiftUI												0x1c97eb474 _UIHostingView.preferencesDidChange() + 412 2	SwiftUI												0x1c98b92cc ViewGraph.updateOutputs(at:) + 180 3	SwiftUI												0x1c9b58e10 closure #1 in closure #1 in ViewRendererHost.render(interval:updateDisplayList:) + 816 4	SwiftUI												0x1c9b582b0 closure #1 in ViewRendererHost.render(interval:updateDisplayList:) + 524 5	SwiftUI												0x1c9b4f1b8 ViewRendererHost.render(interval:updateDisplayList:) + 316 6	SwiftUI												0x1c9c75748 _UIHostingView.layoutSubviews() + 160 7	SwiftUI												0x1c9c75774 @objc _UIHostingView.layoutSubviews() + 24 8	UIKitCore											0x195f657fc -[UIView(CALayerDelegate) layoutSublayersOfLayer:] + 2144 9	QuartzCore										 0x198509494 -[CALayer layoutSublayers] + 284 10 QuartzCore										 0x19850f5ec CA::Layer::layout_if_needed(CA::Transaction*) + 468 11 QuartzCore										 0x19851a128 CA::Layer::layout_and_display_if_needed(CA::Transaction*) + 140 12 QuartzCore										 0x198462b44 CA::Context::commit_transaction(CA::Transaction*, double) + 296 13 QuartzCore										 0x19848c4e4 CA::Transaction::commit() + 676 14 UIKitCore											0x195ada9d0 _afterCACommitHandler + 140 15 CoreFoundation								 0x19197af2c CFRUNLOOP_IS_CALLING_OUT_TO_AN_OBSERVER_CALLBACK_FUNCTION + 32 16 CoreFoundation								 0x191975e20 __CFRunLoopDoObservers + 420 17 CoreFoundation								 0x19197629c __CFRunLoopRun + 968 18 CoreFoundation								 0x191975ba8 CFRunLoopRunSpecific + 424 19 GraphicsServices							 0x19baec344 GSEventRunModal + 160 20 UIKitCore											0x195ab13e4 UIApplicationMain + 1932 21 Kevo													 0x1029d1418 main + 17 (main.m:17) 22 libdyld.dylib									0x1917fd8f0 start + 4
