Bare-metal single disk Xpenology machine 6.2.3 randomly crashed (even after reboot)

[loris_tecnology]

hi everyone

i hope some kind souls can help me.
I have a xpenology machine with a single ironwolf nas drive with btrfs filesystem. Yesterday it crashed, only thing i've done before has been restarting a docker container.
Saw some situation where the data could be accessed read-only, no luck here, even file station doesn't see any files.
I desperately need to copy a personal encrypted folder off of it and i don't have backups. I saw some threads but they leads to nothing cause I can't loose any data. My hope is to force remounting the volume since the hd seems fine or learn a way to copy files off from a live usb or windows pc.

I am running DSM 6.2.3-25426 Update 2

 

if someone knows how to retrieve the data i would really appreciate

I've already tried synologyCloudSyncDecryptionTool but on Windows it can't detect the drive, probably because Windows can't read BTRFS

 

 

Some screenshots that could help

all logs i could find were older than the date of the accident.
