X RAW Studio doesn't work the way you're thinking it does. It's not a tool for importing images from your SD cards (it doesn't have that functionality), it's a tool that allows the .raf (raw) files stored on your computer or external drive to be routed through and processed by the corresponding camera's native X-Processor (the X-Processor 4 in the case of the X-Pro3). This process is similar to processing the .raf files that are on your SD cards in camera (which will save them back to the SD card). Fuji has essentially just re-written the native on-camera raw file processing application for Apple Mac and Windows.
On a side note, it appears that this was a very frustrating problem for you, and I understand that. Words of advice, don't take your frustrations out by blasting the forum for not helping you. Do a little research. Everything I just mentioned above could have been found in the X RAW Studio Features & User Guide (https://fujifilm-x.com/global/stories/fujifilm-x-raw-studio-features-users-guide/) and a little experimenting. That's how I learned it.
