Update:
Checked Windows Event Viewer after another launch attempt.
The crash originates from the AntiCheat service itself, not the game.
Event Viewer entry:Faulting application name: eaanticheat.gameservice.exe
Faulting module name: ntdll.dll
Exception code: 0xc0000374 (heap corruption)
Faulting application path: C:\Program Files\EA\AC\eaanticheat.gameservice.exe
EA Sports FC 25 still launches normally on this same PC.
This means the global AntiCheat service works, but the FC 26 manifest or configuration triggers a heap-corruption crash inside the service.
Please forward this evidence to the AntiCheat Engineering Team, since it confirms a configuration-level bug rather than a local system issue.
