500GB SanDisk Extreme Portable SSD just stopped showing up

My 500GB SanDisk Extreme Portable SSD just stopped showing up in my MacBook ProM1.
When I installed the SanDisk security app, it saw it but said there were no volumes.
It does not show up at all in the disk utility.
I have a lot of video work on this and need it working. Could someone help me, please?
