I have not had the issue, so I can't comment on anything I know has worked or not worked.
When you are using another launcher by default, does it still give you the error?
If not, then I would not worry about it and just keep on using the GO launcher.
If it is creating a problem for you, the only suggestion I can think of is to do a factory reset. TWL is a stock system app, so that may be the only thing that corrects the issue.
Good luck with what you try to do, and let us know how it goes.
