To add onto this, there's a couple of different ways of causing this crash to happen, it is not merely opening the roster. The crashes can happen when you click on any UI elements, including when you click on config, new game, load game, clothing selection, and even when the high poly model of a character is loaded.

Rhedox gave us a build that included this old PR, and it has somewhat reduced the crash (it now takes effort to crash it if you are aiming to make it crash, and you have to do the steps from 5).)
I spent some time trying to figure out what the earliest time is when we can detect that the game is going to crash. It's here.

If "AA2Play.exe"+1C23A8 is hit, the game will crash. The same is true for all of the crashes we've been having, from the UI crashes, to the clothing selection/high poly load crashes. Which looks like:
iVar3 = D3DXCreateEffect(param_1[1],&DAT_00766680,0x7a4,0,0,2,0,ppiVar1,0);
if (iVar3 < 0) {
FUN_00402770(local_cc);
/* WARNING: Subroutine does not return */
__CxxThrowException@8(local_cc,&DAT_0073e158);
}
The closest I could manage to narrow it down is this

Somewhere d3dx9_42.D3DXCreateEffectEx fucks up, and that's what's causing the issues.
Here's an apitrace from when it doesn't crash.
@Arkblade2015 @k4yf0ur Friendly ping. Are you still having this issue with latest dxvk?
The latest dxvk (actually 2.0 or later) no longer has these frequent crashes.
But there is another (and one that is of great concern in this type of game) z-fighting like issue.
Open a new issue please since that's easier to track. Remember to try and get a apitrace of the issue and if you could show it in a screenshot or video that would also be nice 🙂
But you're saying this original crash issue solved? 👀
yes, original crash issue seem to solved.
i will prepare a report on the new issue in a separate.
Nothing extracted yet.
game start and select new game, make class and go class roster (upper right icon).
Double-clicking on a blank field on this screen to add a character or go to the change of clothes screen causes a very high (ABOUT 80%) probability of a CTD, especially after the second person.
