A friend of mine also had this error. It turned out he did not have any Intel Optane memory installed, but yet the Intel Optane Memory and Storage Management software was installed.
Your screen shows "There are no valid disk pairs in your system". Do you know if you actually have any Intel Optane memory installed? My friend uninstalled the Intel Optane Memory software per Dell's recommendation and the error went away. He was using a WD Green SN350 NVMe SSD and didn't need the Intel software.
When there is no Intel Optane memory installed, the Optane Memory and Storage Management software should not report "One of your disks is at risk" since no Optane memory exists.
