BF6 Total System Freeze (Escalated after April 16 Patch)

Account Info: 570+ Hours played.

PC Specs:

CPU: Ryzen 7 9800X3D

GPU: Sapphire Nitro+ 9070XT

Mobo: X870E AORUS PRO BIOS: FB1a

RAM: T-Force 6000MHz C30

PSU: 1000W Platinum+

Issue: Freezing began 2 weeks ago, but since the April 16 patch, it has escalated to frequent, total PC freezes requiring a hard reset every 20-30 mins. This is isolated to Battlefield 6; all synthetic stress tests (Prime95/Furmark) and other games pass perfectly.

Troubleshooting Completed:

Full OS format and clean game/driver reinstall.

Swapped RAM, moved game to different M.2, unplugged HDDs.

Verified 1000W PSU stability with dedicated PCIe cables.

Reset BIOS to defaults; disabled PBO/EXPO.

Tested with iGPU both enabled and disabled.

Passed heavy synthetic stress tests with zero thermal or power issues.

Unfortunately, this issue only occurs in Battlefield 6. I had it two weeks ago, happening every two or three days, but now it happens every 15-30 mins of gameplay. I have attached two crash dumps.
