Hii There,

It appears that you are having trouble with an application that displays a "invalid name" message.  Could you elaborate on the circumstances a little bit?  In particular:

Which app are you trying to open?

Which platform or device—Android, iOS, or Windows—are you using?

Does the error appear as soon as you open the app, or after a specific action?

I can assist in troubleshooting the problem if you provide me with further details!

Thanks
