Assura LVS not running

Hi,

I am trying to do LVS on old design (a simple buffer), but LVS seems to be running indefinitely without displaying an error as below.

When I view the log files (shown below), it does not seem that LVS is progressing.

I am also showing the Assura LVS settings.

It does not seem to be a layout or schematic issue as the circuit has already passed LVS in the past, but LVS stopped working for some reason. I appreciate any input if anyone has experienced this before. 

Thanks!

Note: The issue is for all designs and not just this one.
