Constant reocurring instance crash at ultimatum bossfight POE2

I keep crashing at the bird boss in my ultimatum trials. This is extra frustrating because it has happened 3 times in a row after clearing all the other trials.

I have not yet found out what triggers it, the last 2 times I was charging perfect strike or blocking. No other area in the game has me me crash. I can also not use my bug report ID because it is instant.


Edit: switching to vulcan instead of directx12 fixed this for me!

Same here but at the second boss in ultimatum trail.

I also just crashed at the ultimatum bird boss on wave 5. Entered the arena, the moment the boss began their red projectile vomit or whatever, game froze and then auto closed after about 15 seconds. Really felt like insult to injury, given that I was having to run ultimatum to begin with. Bricked the run, I just rage quit when I logged back in to see I'd have to restart.

yep same here. finally got my build up to snuff i could handle ultimatum to a degree, finally reach the boss and start killin it quite quickly, game crash.

but the boss isn't the only place i've had a game crash the 2nd arena with the blood pool has caused me to crash as well when things spawn in and i start dropping frost wall everywhere.

edit: i looked over the logs. worth mentioning this comes up a LOT but only 2 instances of it after i started the boss fight with no logged reason for crash otherwise:

[WARN Client 352] Tried to SetExtraActivationRangeAroundTile() after level generation was complete

figured i'd update after the patch, i was able to get through the first ultimatum run with no crash related issues. anyone else able to make it through crash free or people still crashing?

Yep, me and a friend both crashed while in party on the bird boss as soon as the second health bar appeared. So it is still happening.

It happened to me both on the 7th wave and 10th wave, switching to vulkan didn't fix it either.
For me the crash appears when he tries to launch an attack at melee range (cant see which one)

This really is a blocking bug for me since it prevents me from getting my ascendancy - as my build cant do sanctum (on top of this bug happening after 15min of an overwhelming challenge)

Crashed just now on bird boss in cruel difficulty........

same problem.
Always crash on Round 9 and 10
Can't complete my Ascendancy :(((

It's the same issue they had with PoE1 crashing when specific effects are all kicking off. Really disappointing it's still a thing.
