Run() is asynchronous, so if Fortnite opens/closes quickly you can end up with overlapping powercfg invocations and a race where the earlier launch command finishes after the close command (leaving the wrong power plan active). Consider using RunWait() (or capturing the PID and waiting for it to exit) for both powercfg calls to guarantee ordering.
