Potential fix for multithread crashing issues from 24H2 Win update

Hi GGG and community,

In relation to this:

New: Investigating cases where some players experience crashes related to Multithreading and have to restart their PCs. This seems to mostly be for players with the Windows 24H2 update.

-----------

I have been plagued with this issue when portalling between zones, it seems as though the CPU is spiking which causes a system crash. It is worth noting that durning my troubleshooting, ive obeserved this issue happens too a number of games, not just POE2.

Some workarounds have been the likes of disabling multithreading or setting affinity for poe2 process in task manager, turning CPU 0 and CPU 1 off, this allows you too enter the task manager in the event of a crash.

These were previous steps id personally taken in working around, however, Windows seems to have addressed this issue in a recent, optional Windows update.

The update is KB5048162 and is found in the optional updates section on the Settings/Windows update. KB5048162 patchnotes seemingly address this issue and will likely be deployed in the next feature update. The patch notes are as follows:

----

Summary
Security Improvements

There are no new security improvements in this release. This update is cumulative and contains all previously released security improvements.

Quality and Reliability Improvements

.NET Runtime

- Addresses an issue where in rare cases where an infinite loop could occur when a thread enters CLR for the first time.

----

I have since updated to the new optional update and tested portalling ingame extensively, i have not crashed since.

I hope this helps anyone affected, this seems to be a permenant fix.

Kind Regards

Jammies

Apparently worked for me as well, had 0 crashes during 3h of testing.
Thanks Jammies!

Nice, good to hear.

I have the update installed and still the game crashes for me with 7800x3d and 4090 :'(

Is it the same type of crash though? Since I've applied the update and restarted, I've not had the issue again. CPU is stable at around 25% at all times

My CPU is around 28-30% usage while playing.

Also I checked my update history, I already have KB5048162 installed (yesterday) and I am still crashing to desktop on a regular basis.

Hi same issue.. tried 4 times this morning and PC keeps freezing so force restart..

unable to play now

Crashing to desktop isn't the same type of crashes or symptoms caused by this 24h2 mutlithreading issue.

These crashes physically crash the computer and have to force a reset of the device.

If you turn multi threading off from the in game settings and you are still crashing, then it certainly isn't the same. I'd suggest raising a ticket with GGG.

Well, must correct myself here. Game just crashed in exactly the same way as before. Might have received a bit more time due to the update, but it's not a proper fix after all.

so its reduced the likelyhood of the crashing occuring, probably why its an optional update as there is still the potenital for crashing the first time a thread enters CLR.

Either way, its not an issue with GGG, this is happening over mutiple games, windows should release a permenant fix for it.

I still havent crashed since i implemented the update. So even if i do crash now, i would have crashed atleast 10 times by now, so its a win either way.
