Battlefield 6 Open Beta – Critical PC freeze

Hello,

In Battlefield 6 Open Beta my PC randomly hard-freezes:

Monitor loses signal

Keyboard & mouse turn off

Fans keep spinning

Power button doesn’t respond – only PSU power off helps

This happens only in BF6 Beta. Other heavy games work fine.

My setup:

Windows 10 Pro (latest updates)

AMD Ryzen 9 5900X

NVIDIA RTX 4070 (driver 580.88 – 31 July 2025)

32GB DDR4 3600MHz RAM

Motherboard: B550M (BIOS version unknown)

PSU: Be Quiet! 650W

No overclocking

Tried: Disabled DLSS & Reflex, changed graphics presets, switched between fullscreen/borderless, clean driver reinstall (DDU) – no change.

Thank you.
