Battlefield 6 PC crash on startup – Error 0x00001338 (KERNELBASE.dll)

Hello, I am experiencing a persistent crash with Battlefield 6 on PC before reaching the main menu. The game closes during startup and appears to fail during anti cheat initialization. I have never used cheats, hacks, mods, or exploit tools. My system is stable and other games work normally. For transparency, before this issue started I used Microsoft Process Monitor only for diagnostic purposes while troubleshooting a crash in Call of Duty Black Ops 3. I accidentally left ProcMon running once and Battlefield warned me to close it before launch. I closed it immediately. After that Battlefield 6 began crashing on startup. ProcMon has since been fully uninstalled. I have already tried reinstalling the game and anti cheat, clearing cache, restarting multiple times, verifying Secure Boot is enabled, confirming kernel debugging and test signing are off, disabling Hyper V and virtualization, uninstalling VPN software, and cleaning NVIDIA caches. The issue still persists. I believe this is a false anti cheat kernel level block and would appreciate assistance checking whether my system or account is being prevented from initializing anti cheat correctly.
