Avira Rescue System not working on NWMe SSD

Hi,

I've tried to use Avira Rescue System (the latest version today: http://www.ubuntu.com/getubuntu/releasenotes?os=ubuntu&ver=20.04.3&lang=${LANG} ) on a laptop with MWMe SSD (Kingston OM8PCP3512F-AB) and the scan don't work.
All starts well, I even can update, but when scanning it open an error box about cannot use split on undefined variable...
In fact, on /media I don't see the system disk, only the external disk.

It seems the MWMe SSD is not detected on the Linux ?

Do you know if there is a known problem ?
