Hard freezes + 0x133 since EA Javelin Anti-Cheat (9800X3D + 5070)

Since the new EA Javelin Anti-Cheat was added, Apex causes full system freezes (main menu, loading, or in-game, even when idle/minimized in lobby). PC freezes for 1–2 minutes, then shows a glitched/partial blue screen and either restarts or powers off.
Only happens in Apex.

Error codes:

• Bugcheck: 0x00000133 (0x1, 0x1e00, ...) – DPC_WATCHDOG_VIOLATION
• Event Viewer: Kernel-Power 41, nvlddmkm timeout (Event 153), TPM Event 15

Specs:

• CPU: Ryzen 7 9800X3D
• GPU: RTX 5070 (latest drivers, clean installs with DDU)
• RAM: 32GB DDR5 (tested 6000 → 5600 → stock)
• Motherboard: ASUS TUF Gaming B850-Plus WIFI
• OS: Windows 10
• Game on SSD, DX12

What I’ve already tried:

• Full Event Viewer analysis
• SFC / DISM (clean)
• Disabled TSME (SMEE)
• Memory Context Restore experiments
• Power Supply Idle Control set to Typical Current Idle
• VDDSOC negative offset (settled at -0.020)
• Cleaned all Steam/EA launch options
• Wiped manual DRAM timings → Auto/DOCP
• Lowered RAM from 6000 MHz to 5600 MHz (FCLK 2000) and stock
• Multiple clean NVIDIA driver reinstalls with DDU
• Verified game files

Issue still occurs even when the game is idle in the lobby under these conditions.

Minidump available if needed. Happy to provide any extra logs.

Any known issues with Javelin Anti-Cheat + 50-series cards or 9800X3D? Any recommended workaround while this is being looked at?

Thanks.
