Crash after 15/20 minutes

Question

I’m experiencing repeated crashes in EA SPORTS FC 26, with the game generating .mdmp files each time it fails.
WinDbg analysis shows memory access violations (Access Violation) related to the SoftMaxNormalize function and the AntiCheat Virtualization module.
The issue appears to be caused by an invalid or uninitialized pointer within the game or anti-cheat code and occurs consistently after about 15–20 minutes of gameplay.

I already tryed all the solutions give me by EA and by Chat gpt, but still I cannot play.

1_Crash Type: INVALID POINTER READ

Exception: 0xC0000005 (Access Violation - Read)
Faulting module: FC26!ANTICHEAT_VIRTUALIZE_CODEMARKER_SHIELD
Instruction:

add rsi, qword ptr [r8+rcx*8] Address attempted: 0x000000008033F318 (invalid)

Failure Hash: {4613b1cb-f4ba-2b7f-df7e-c3a2456779ab}

2_Crash Type: INVALID POINTER WRITE

Exception: 0xC0000005 (Access Violation - Write)
Faulting module: FC26!SoftMaxNormalize+0x68FCD8
Instruction:

mov qword ptr [rcx+0x10], rdx Address attempted: 0x000000010000000F (invalid)

Failure Hash: {7e406522-5a1d-a46a-1ef8-dd88aaa3c2b9}
