Clone/Image internal Apple SSD which keeps disconnecting

I'm trying to do data recovery on an internal APFS-formatted Apple SSD (MacBook Pro), but it keep ejecting/disconnecting when I try to do so. The same happened when running byte-to-byte backup in DiskDrill, and I though my problem would be solved using HDDSuperClone, but the same happened. Whereas DiskDrill was only able to get to 4.64GB, HSC got to 15GB on the first attempt.

As I'm trying to avoid putting any unnecessary stress on the internal SSD, I'm trying to figure out how to fix this problem. HDDSuperClone has many complex and advanced features, and I believe there are some parameters I can turn on to resolve this problem... I just don't know which ones.

For clarification purpose, when I say it keeps ejecting/disconnecting, I mean it's not visible even when running
sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL in HSC Terminal (sda completely disappears) or ls /Volumes in macOS Terminal

Start with the reported APFS internal Apple SSD disconnections and the comparison between DiskDrill and HDDSuperClone progress. No source files, tests, or entry points are identified; the issue would be actionable only after isolating a reproducible cause and defining which HDDSuperClone behavior or parameter should change.
