Dead Space Remake does not launch – EA App restarts

HI!
Dead Space Remake does not launch on my PC. When I click Play, deadspace.exe starts briefly and then closes immediately, sending me back to the EA App.
I have already tried:

EA App / Game environment:
- Reinstalled EA App after manually deleting AppData and ProgramData
- Fully reinstalled Dead Space Remake
- Cleared EA App cache, ran App Recovery
- Used the "Repair" option on the game
- Tested with two different EA accounts
- Tried launching in EA App offline mode

Windows / System settings:
- Latest NVIDIA driver installed for RTX 5070
- BIOS tested with dGPU-only mode
- Secure Boot enabled
- Windows Defender fully disabled
- Controlled Folder Access / Ransomware Protection not enabled
- Compatibility mode removed from deadspace.exe

External software / conflicts:
- Disabled all overlays (Discord, GeForce Experience, MSI Afterburner, etc.)
- Uninstalled NordVPN completely (including kernel drivers)
- No other network filters present

Diagnostics:
- DxDiag confirms DirectX 12.2 support
- Event Viewer shows no application crash entries
- Crash dump collection enabled, but no dump is created
Using Process Monitor I traced the startup. Every time the game attempts to load:
D:\Játékok\Dead Space (2023)\Core\Activation64.dll → FILE LOCKED WITH ONLY READERS
After this, deadspace.exe exits with no error message.
This shows the problem is with the DRM module (Activation64.dll) failing to initialize or being blocked incorrectly.

Complete Procmon logfile showing the Activation64.dll lock

Please review and provide a fix or replacement for the DRM/activation module, because this issue is reproducible across clean installs and different accounts.
Thank you.
