Hello.
When using Heroic Games Launcher on macOS, starting a game installation triggers a bug where an excessive number of “legendary” backend processes are spawned instead of a normal single or small set of workers; initially, each process consumes very high CPU (around 30–40%), causing significant system slowdown, and even after force-quitting and restarting the application, the issue persists in a reduced form where 10–20+ “legendary” processes remain active simultaneously but do not terminate, a loop in download/sync handling, as the problem consistently appears right when initiating an install and continues despite clearing cache files, restarting the app, and reinstalling, leading to unnecessary resource usage and degraded user experience.
Thank you for your help
