no icon after ejecting

i removed sandisk after clicking eject on mac.

then i saw the message saying i hadn’t ejected it before removing from computer.

now when i reinsert the sandisk there is no icon showing.

after restarting computer, i tried starting over from the beginning by downloading the software again and re-running the manager but it says i need to run the sandisk secure access from a sandisk external device. i’d love to do that but can’t access it because now there is no icon showing. the sandisk is lighting up intermittantly. what do i do now?

Try connecting this to another MAC ofr desktop. Sometimes, the issue lies on the computer itself.
