Recover crashed disposable vm?

I am assuming qubes does a good job of wiping closed disposable vms but… I had a lot of unfinished work in a dispvm that crashed (maybe because of lack of space or ram or cpu I don’t know).

Is there any way to access the files that were saved when the dispvm crashed? I had a lot of structured downloads in files from firefox.

Thank you in advance

Maybe the LVM volume still exist.

Is is no longer listed when I run ‘sudo lvs’
