Strange link named Developer on Desktop

In my code I copy 2 executable files to the Desktop (selected via NSOpenPanel). I am using Xcode 13.2.1

On an Intel Mac this works as expected and I see the 2 files on the desktop as expected.

On an M1 Mini I see a link file called Developer. When I click it the 2 copied files are revealed. If I only copy one file then it shows as expected. This happens in both Monterey and Big Sur but only on the M1.

Saving the files to any other folder does not create the Developer link, only when Desktop is chosen from the selection dialog.

When I execute ls ~/Desktop from the command line I see only the 2 files, so I am thinking that Developer is some artefact of the Finder.

Is the creation of this 'Developer' link a System/Finder setting and why would it only happen on the M1 machine?

	{
		let panel = NSOpenPanel()
		panel.message = NSLocalizedString("Export Command Line Tools", comment: "")
		panel.prompt = NSLocalizedString("Choose", comment: "")
		panel.canChooseFiles = false
		panel.canChooseDirectories = true
		panel.canCreateDirectories = true
		panel.showsHiddenFiles = true
		panel.isExtensionHidden = false

		let result = panel.runModal()
		if result != .OK { return }

		guard let dir = panel.directoryURL else { return }
		let dest = dir.path

		let fileManger = FileManager.default
		for file in ["a", "b"] {
			do {
				let target = dest + "/" + file
				if fileManger.fileExists(atPath: target) {
					try fileManger.removeItem(atPath: target)
				}
				guard let util = Path.executablePath(forExecutable: file) else { return }
				try fileManger.copyItem(atPath: util, toPath: target)
				Logger.instance.log("Copied: " + file + " to: " + dest)
			} catch {
				Logger.instance.log("Failed to copy: " + file + " to: " + dest)
			}
		}
