Yeah this is something I didn't get to test properly, I only tested removing games in uLaunch without doing the actual removal in stock, this needs proper handling
This build should fix the issue, I tested by deleting a game with uLaunch disabled and the menu entry should also be deleted automatically re-enabling uLaunch
Steps to reproduce:
Using uManager "Reset menu entries" helps deleting that, but imo this shouldn't either be shown or not be launchable at all to not hang OS.
