Hello, I have an app, which runs fine on Monterey, but crashes on Big Sur. However, I am able to run it on Big Sur from XCode only.

There are some pictures(please open them in new tab) from Zombie instrument:
Regarding Zombie, it looks like some error happens in this code in
@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate, Loggable
is the method
fileprivate func handleFSE(event: NSAppleEventDescriptor?, replyEvent: NSAppleEventDescriptor?) {
Defaults[.deepLinkData] = event?.paramDescriptor(forKeyword: keyDirectObject)?.stringValue
Defaults[.isFromCUSLaunch] = true
if let window = WindowControllerFrom(storyboard: .cus, withIdentifier: .cusWindow) {
logIfCan(string: "Deeplink data: \(event?.paramDescriptor(forKeyword: keyDirectObject)?.stringValue ?? .empty)")
let cusVC = CUSViewController(event?.paramDescriptor(forKeyword: keyDirectObject)?.stringValue ?? .empty)
window.contentViewController = cusVC
if let screen = NSScreen.main {
window.window?.setFrame(screen.visibleFrame, display: true, animate: true)
}
window.window?.makeKeyAndOrderFront(nil)
}
}
WindowControllerFrom returns NSWindowController? and CUSViewController is a class which inherits from AbstractViewController.
I would appreciate any idea what can be wrong here, and why there is no problem on Monterey (both M1 and Intel), but crashes on Big Sur?
