Battlefield 6 Open Beta crash and crash dump mentions MSTTSEngine_OneCore.dll

I'm experiencing a crash in the Battlefield 6 Open Beta that I haven’t seen reported anywhere else, and I'm hoping someone here can help.

On pre-load day, I updated my GPU driver to the latest version. The game launched successfully, I went in and changed some settings, then exited normally.

However, the next day, when I tried to launch the game again, it entered fullscreen and reached the **“Connecting to servers”** screen—then crashed to desktop without any error message.

Since I’m in a region where a game accelerator (VPN-like proxy) is required to connect to Battlefield servers, I suspected that might be the issue. I tried disabling the accelerator and all proxies and launched the game again. This time, it didn’t crash, but it also couldn’t connect to the servers. This made me think the crash is not network-related, but rather something going wrong during resource loading.

Then I switched to downloading the game from the EA App instead of Steam. After that, the crash started happening **even earlier**—right after the studio logo screens, exactly when the theme music ends.

I’ve tried a lot of things since then, including:

1. Rolling back the GPU driver to the version officially recommended by EA.
2. Verifying game file integrity, changing the game language, reinstalling EA Anti-Cheat.
3. Closing nearly all background apps, especially monitoring/tweaking tools—only the game accelerator was left running.
4. Following Reddit and EA forum suggestions: created a new admin Windows account, changed Windows Security settings.
5. Fully deleted the game’s config files and even dug into crash dumps with WinDbg and ChatGPT.

The crash dump analysis showed (full in attachment) :

Exception code: `0xC0000006` — STATUS\_IN\_PAGE\_ERROR

Fault module: `MSTTSEngine_OneCore.dll` (Microsoft Text-to-Speech engine)

ChatGPT interpreted this as the game trying to access a memory page that had been swapped to disk, but the system failed to retrieve it—causing a crash. It suspected faulty RAM or storage, but I ran tests and both seem completely fine.

My system:

CPU: Ryzen 7 5800H

GPU: RTX 3060 Laptop

OS: Windows 10 22H2

Secure Boot is enabled by default (laptop)

If anyone can help interpret the crash dump or has encountered a similar issue, I’d really appreciate discussing it with you.
