I get the same error “invalid device state” when launching from XCode.

Do you have ios-sim installed? npm install ios-sim

I do, I fixed the error by reinstalling Xcode.

How do you reinstalled the xcode? I already looked everywhere to find how to uninstall , so i could install again. Did you just installed over the old one?

Deleted the .app in Applications folder.
