Sandisk extreme V2 password

Hi,
Can’t get access to my brand-new SSD:

  • formatted the SSD - APFS (Encrypted)
  • when I plug in the SSd it asks me for a PSW via SunDisk unlock app.
    I’ve never set a psw for that, and now I can’t get access to my data

Is anyone having the same issue/found a fix?

Thanks
