Potential Memory Leak due to Unremoved IPC Listeners

[Imran-imtiaz48]

The setMenus() method registers new IPC listeners every time it is called, but it only removes the old ones if this.commands is already defined. If setMenus() is called repeatedly with new commands or if removeAllMenus() is not triggered properly, old listeners may remain attached to ipcRenderer, leading to duplicated event handling and memory leaks.
