When viewing Manage Promoted Items in the User Navigation (frontend), I'm getting the following Theme Error:

The error log is as follows:

It seems that if an item has been promoted, and the application has either been disabled or not installed, then it will throw an error causing the template error.

Thank you for bringing this issue to our attention! I can confirm this should be further reviewed and I have logged an internal bug report for our development team to investigate and address as necessary, in a future maintenance release.
