Sounds like something indeed went wrong. Can you confirm what app did you try to uninstall, was it Asus Aura? And do you happen to remember what kind of paths relating to it were not removed? Also, to confirm, did you run the uninstallation with the default settings?
This sort of issue can happen due to many reasons, such as files being still in use or otherwise protected against removal. But it's difficult to say yet. If you can help me to reproduce the issue, I can analyze it properly and if it is a bug in Uninstalr, I can fix it.
