Title Armored Core 4 BLUS30027 Crashes during "simulator" battles

[Caladain]

Please do not ask for help or report compatibility regressions here, use RPCS3 Discord server or forums instead.

Quick summary

After a "Simulator battle" the game crashes with an access violation.

Details

Load up the save, go to ACSIS, Simulator, Select the first pack, Select No32, fight. Defeat No32, crash after the completed window pops up.
It's not a 100% repro, sometimes it crashes, sometimes it doesn't. Might be a race condition?

1. Please attach RPCS3's log.

The are settings i use:

PPU decoder: LLVM
SPU decoder: LLVM
thread scheduler enabled
Spu loop detection enabled
Spu cache enabled
TSX enabled
spu block size: safe
Spu threads: 4 (should be enough to put auto instead)
Vulkan renderer enabled
anisotropic filter: auto
Anti-Aliasing: auto
Asynic shader mode
Shader compiler threads: Auto
Onl;y white colour buffers enabled
(Resolution scales and threshold should be default)
Accurate RSX reservation access enabled
firmware settings: Load liblv2 only
Read depth buffers enabled
Write depth buffers enabled
Read color buffers enabled
Max LLVM compile threads should be the maximum your cpu can provide.

Try these settings and see if they work.

Confirmed the crash still happens with those settings.

@Caladain this issue and #9387 have the same error message so its probably same issue might be better if you combined the armored core 4 issues into just one big issue. Then close the others.

played through all simulator battles without the game crashing even once, this is either fixed or extremely rare now
