Reposting/updating from my other thread stuff here just to centralize.
DXDiag here.
Here is a relevant save.
The crash I'm experience is a direct crash into a reboot. It skips the BSOD or any other obvious fault notification. The time of the hang between the game and the reboot is noticable, but short (a second or two). This crash only ever happens during the transition to and from the campaign map. I've had it right as my army reached an enemy army and teh game tried to transition campaign->pre-battle screen. I've also had it post-battle after telling the opposing leader that they were my prisoner now. At the transition point from that conversation screen back to the campaign map, crash-reboot.
Above is a save where this happens predictably. The save is on the pre-battle screen. The crash happens every time in this save whether I simulate the battle (Send in troops) or fight and win it myself. The crash/reboot happened multiple times in a row using both circumstances. With tihs particular save it has happened since 1.07. I have tried it with 1.08 and 1.09. I was seeing the crash earlier in the same circumstance, but it wasn't all the time. I'm not sure if it started 1.05 or 1.06. For this particular save I have never been able to move passed this point in this particular save without a crash.
I have done memory diagnostics and whatnot. Everything is up to date. In my spare time I'm going through Event Logs around the point of crash to look for non-Bannerlord reasons, but haven't found anything. I routinely have GPU and CPU temp monitors up on a second screen. I have a PSU with a status monitor. None of those are showing any issues. The commonality seems to be specifically transitions to and from the campaign map. I haven't seen it happening in any other game.
