I spot at least one LVS related change in today's / yesterday's openlane
develop
commits, it's definitely not that? Or it just started breaking with no openlane change on your end?

I did update openlane so it could be related.

interesting that LVS got crashy on your end. I did a recent run of my design and still no LVS issues, just tons of antenna/DRC dialing density down to 0.2 with plenty of die area, insertion strategy 1, still got about 80 violations here..
then there's chatter elsewhere about these antenna violations being a sliding scale of "bad" depending on the ratio of violation, not sure if mine are just mildly bad, or unnacceptably bad for the shuttle

If you run
magic_antenna_check
in interactive mode, you get a number for each violation ... max value is in theory 400.
BTW, got LVS fixed ... it was a bad interaction between recent LVS changes in openlane and my custom flow script.
