I try to start FreeBSD but I got this error:

Is a localhost and I used FreeBSD 11.4
Is there any chance to recover data from this FreeBSD?
I read some topics about this error, but I am really new with this OS and I don't know what exactly to do.
Thank you for your time !

attach an install CD to the VM and boot from it as live fs or something.
then try to inspect your pool

Boot from something working.
Then, you can run commands like:
zpool status
zpool list -v
gpart show -p
