Sandisk secure access files are missing after signing in! HELP PLS


Sandisk Ultra Usb 3.0
I’ve had this USB for many years. I recently wanted to go and check out some important files. I went ahead and logged in and all my important files are missing. It only shows one folder that says “Usb Flash Drives” with a red x as you can see below. Can someone please help me get my files back.
