My home assistant won't boot using virtual box

I have a virtual box installation of Home Assistant OS that has been running for a year or two but now it won’t start. When I hit start in Virtual Box, it flashes the following message very briefly and then goes black. It keeps flashing this in this cycle over and over but doesn’t boot. Does the error message in this screenshot make sense to anyone? Thanks.

Did you just update to HAOS 8.0?

yeah, i think i did. didn’t even look at the version number. does this break HA?
