Can’t help but I just did this myself. Was a fairly fresh install so I didn’t lose anything other than have to reconfigure some stuff and install some things.
Buuuuut
What happened dto me was something crashed during the update and my computer went to a black screen. So I just left it for a bit to hopefully finish even without the display. Turned the computer off and my nvme was just gone. Ended up having to get a new one.
