Sudden Game Crashes During Ultimatum Trials since Yesterday

Hi,

I'm using a Windows 11 system with an i7-13700kf CPU and a 4070Ti GPU. I've been playing daily since the start of the new season without any issues. However, starting yesterday morning, my game has begun crashing during Ultimatum trials—specifically, about 3 crashes in every 6 trials. Other game content runs smoothly with no problems.

When the crash happens, the game suddenly stops and quits on its own without any warning or error message.

I haven't made any software or hardware changes before the crashes started yesterday. After noticing the issue, I updated my Nvidia drivers, updated my BIOS, and ran PackCheck (all content hashes are in sync), but the problem persists.

Interestingly, a friend of mine is experiencing a similar issue with crashes, though his crashes occur in other contents. He switched to the Steam version of the game and hasn't encountered any problems since then.

Here are my game settings:

Display Settings:

Render Resolution: No Upscale - 2560x1440
Mode: Windowed Fullscreen
Renderer: DirectX12
V-Sync: Off
Triple Buffering: Disabled
Foreground FPS Cap: 150

Detail Settings:
Upscale mode: off
Shadow quality: High
(Others are set to default)

Advanced Settings:

Dynamic Culling: Enabled
Dynamic Resolution: Disabled
Engine Multithreading: Enabled

I'd appreciate any assistance you can provide to help resolve this issue.

Thanks!
