In this case, I backed up from the partition formatting confirmation screen, changed my mind, and then changed the / partition (root) to be formatted but not encrypted. This crash resulted.

When I reran the installation, I didn't change the pre-selected option for / to be formatted and encrypted, and things proceeded normally.

I had an unrelated crash during an install on a VM using a single encrypted VM. When I started a re-install, I didn't destroy or clear the virtual disk, requested reformatting of all LVs/partitions and once again, specified encryption on a single LV.

I got this crash after setting the disk layout.
