Crash When Clicking on Definition View Created by AppKit's showDefinition(for:at)

I'm encountering a crash issue in my macOS application when clicking on the view generated by AppKit's showDefinition(for:at) function. I'm seeking assistance to resolve this issue.

Problem Description: I'm developing a macOS application where I utilize the showDefinition(for:at) function provided by AppKit to display the definition view of words. However, whenever I click on this view, the application crashes abruptly.

Error Message: The crash log reveals the following error message:

Fault: deferNSXPCInvocationOntoMainThread_block_invoke caught NSInternalInconsistencyException '_CPSSetFrontProcessWithOptions failed due to CGError -606 4294966690 fffffda2 (appIsDaemon)'

Attempts Made:

Tried wrapping relevant code blocks with DispatchQueue.main.async, suspecting a threading issue.

Making the DefinitionWindow variable a global one to manually control its lifecycle

Development Environment:

macOS Version: 14.3.1 Xcode Version: 15

I've included a snippet of the function where the view is created:

func ShowDefinition(selectedText : String) {
        DispatchQueue.main.async {
            let DefinitionWindow = NSWindow(contentRect: NSRect(origin: self.mouseLocation, size: NSSize(width: 1, height: 1)), styleMask: [.borderless], backing: .buffered, defer: false)
            DefinitionWindow.level = .floating
            guard let mainScreenFrame = NSScreen.main?.frame else {
                return
            }
            DefinitionWindow.contentView?.showDefinition(for: attributedString, at: pointInWindow)
            DefinitionWindow.orderFront(nil)
            
        }
    }

Potential Questions and Concerns:

Could there be an issue related to UI transitions or the main thread?

How exactly does the showDefinition(for:at) process work internally?

Maybe , the view's display level being raised when clicked caused conflict?

If anyone could provide any insights or guidance on resolving this issue, it would be greatly appreciated. Thank you!
