What do you mean "there is an error"? Does the above message appear in the console? Do you get an alert?

I found this:
<http://www.thexlab.com/faqs/error-10810.html>
"One cause of this error is that the Mac® OS X process table is full."
I haven't read the whole article, but it suggests that either your app or some other app is filling up the process table. It does say "One cause", not "The only cause", so it's possible you have a different problem, but this is the first thing I'd check.
You don't mention whether you tried Google. I did but got lucky. The first thing I searched for was "OSStatus error - 10810" (without the quotes) and the above link was the first result. If I had Googled for the whole message "The operation couldn't be completed. (OSStatus error - 10810)", the results would have been less useful.
When I Googled for "10810 site:developer.apple.com" (or searched for "10810" in the documentation, using Xcode) I only found the Launch Services Reference, which only told me the error means "An unknown error has occurred."
<https://developer.apple.com/library/mac/#documentation/Carbon/Reference/LaunchServicesReference/Reference/reference.html>
This is consistent with a full process table being one possible cause, not the only one. But it's the first thing I would check for.

It's good that you showed your code, but you know, you don't have to take a screen shot. You can just paste the actual code into email. :) Easier for you and easier for us, because we may want to show how to fix your code. If I want to do that I have to type the code myself, reading from your screen shot, instead of just copying it.

How do you know this? The docs for NSWorkspaceLaunchConfigurationArguments say "Ignored if a new instance of the application is not launched." So maybe the app isn't getting launched.

I ran the command "ulimit -a", which I got from the article I found. On a 10.6.8 system it shows 266 as the max user processes, which matches what the article says. However on a 10.8.3 system it shows 709. This might explain why you don't run into the problem on 10.8.x.
