POE 2 Buffer Underflow

The same problem with my main...

The problem is urgent...

Crashing here too.
Traitor's passage area on the 2nd playthrough.
I just did the ~500mb update before starting. Doing driver updates, and already did steam file verification.

Logs did have this though:

"

Those were the last messages before crash. the `CRIT` log message might be a thing. It doesn't sound serious (who cares about steam achievements), or at least not serious enough to die and go to desktop :(

Check your own <steamapps>/common/Path of Exile 2/logs/Client.txt file for anything. It will help the devs tremendously. Nothing's worse than a message saying "it's broken" for a dev to go debug something :)

Can't load into the game with my character at all after the Steam update moments ago, just gives buffer underflow error and exits game.

GGG Just posted another ~300mb patch, my character loads now!

I'm terribly tired of constantly crashing due to being up to date (24h2) and now on top of it, I'm getting buffer underflow crash. When will this be addressed because this is seriously driving me insane. We've never gotten an answer yet from GGG about those problems. This is a major issue and it's like they're completely ignoring it. Step it up. You've got a great game going when it works!
One more thing, when it crashes, it crashes my whole PC... not just the game! I have to make sure every time I open the game to untick CPU 1&2 incase it crashes so it doesn't affect my whole pc being frozen!! This is not good on my equipment. Please fix this issue asap...
