Can't update function

[jiaping]

I have a function: __int64 __fastcall sub_1800043D4(PVOID Parameter) { HWND v1; // rdi char *v2; // rsi wchar_t *v3; // rbx HDEVNOTIFY v4; // rax void *v5; // rax void **v6; // rbx void *v7; // rcx void **v8; // rsi HDEVNOTIFY *v9; // rbx _QWORD *v10; // rcx _QWORD *v11; // rbx MSG Msg; // [rsp+60h] [rbp-78h] BYREF char v14[64]; // [rsp+90h] [rbp-48h] BYREF char v15; // [rsp+D0h] [rbp-8h] BYREF
