Depending on how important your data is to you you might want to start by cloning the disk. (I'd recommend clonezilla for ease of use.) You can check that your data is safe by booting from a live image - kali, knoppix etc. Then try to mount your Qubes partition - you'll need to use cryptsetup luksOpen to decrypt the disk, and you should then be able to mount the partition. You don't say whether you are using 3.2 or 4.0, and the approach to take will depend on that. In 4.0 individual qubes by default use thin pools so you will need to identify the qubes you are interested in and check in /dev/qubes-dom0 using 'ls -l' which of the device files in /dev match. You can then mount those devices and copy out the data. Once you've secured all your data, you can try for recovery of the system. I've had some success in doing this but frankly it's almost always better to reinstall, particularly as you don't know *what* went wrong. If you've got recent backups or don't care about the data, I would just skip those steps and reinstall. If you need specific advice give a little more detail about how you had the system configured and exactly what steps you've taken so far.
