sorry to hear about the PC crash, never fun, and backups if any are rarely current (my own experience)
Ideally the log files point exactly to the issue. And in fact they might be doing just that. To me though, its still alot of confusion, sadly.
the recent attempts at trying to get the new map up and running, with default settings, would have been my attempt at reducing the unknown variables
and no mods.
The ideal is that plain vanilla starts up fine, allowing progressively adding changes until the trouble spot is encountered. Kind of backing in to the issue eventually.
sounds like you've tried all that though(?) Something is corrupted, not sure if its hardware issues that could be at fault, ssd/hdd/memory check?
Got another machine to try with lol ahem.
