Then that means the dongle you own is the RCM Loader although there are multiple models of it so if you want to know exactly which one you have, you can check on their
website. Anyways, as I said earlier, this dongle reproduces the act of sending a payload from a device through a USB cable. If that still doesn't make sense, then just follow the whole guide until the end and hopefully, you'll understand what steps the dongle replaces. Also since you have AutoRCM enabled, you can skip any steps involving booting into RCM because, as the name implies, this setting AUTOmatically launches the console into RCM.
Well, objectively there is no reason why it shouldn't be working. Try reinstalling the game, DLC, and updates to see if that changes anything.
