Game crashing a lot since +1 month

[toxiicdev]

Describe the bug

A lot of mta players playing on DM servers (deathmatch races), most of those crashes are invalid access exceptions, or random crashes

Steps to reproduce

Just play for a bit on servers with a lot of mods (infernus, draw distance, etc)...

Version

Any after november 2025

Additional context

I wonder if you could add something like a VectoredExceptionHandler in the injected dll's to prevent crashes, and automatically report them to mta devs

example of a code i did time ago on a x86 game that was having similar issues:

LONG WINAPI CustomExceptionHandler(PEXCEPTION_POINTERS p)
{
if (p->ExceptionRecord->ExceptionCode != STATUS_ACCESS_VIOLATION)
return EXCEPTION_CONTINUE_SEARCH;

CONTEXT* ctx = p->ContextRecord;
DWORD eip = (DWORD)p->ExceptionRecord->ExceptionAddress;

char buf[1024];

wsprintfA(buf,
    "Access violation at %08X\n"
    "EAX=%08X EBX=%08X ECX=%08X EDX=%08X\n"
    "ESI=%08X EDI=%08X EBP=%08X ESP=%08X\n"
    "EIP=%08X\n",
    eip,
    ctx->Eax, ctx->Ebx, ctx->Ecx, ctx->Edx,
    ctx->Esi, ctx->Edi, ctx->Ebp, ctx->Esp,
    ctx->Eip);

Log::Write(buf);

// ================= STACK DUMP =================
Log::Write("Stack dump\n");

DWORD esp = ctx->Esp;

for (int i = 0; i < 256; i++)
{
    DWORD addr = esp + (i * 4);

    MEMORY_BASIC_INFORMATION mbi;
    if (!VirtualQuery((void*)addr, &mbi, sizeof(mbi)))
        break;

    if (mbi.State != MEM_COMMIT || (mbi.Protect & PAGE_NOACCESS))
        continue;

    DWORD value = *(DWORD*)addr;

    wsprintfA(buf, "[ESP + %X] -> %08X\n", i * 4, value);
    Log::Write(buf);
}

// ================= MODULE ==================
Log::Write("Module:\n");

HMODULE mods[512];
DWORD needed;

if (EnumProcessModules(GetCurrentProcess(), mods, sizeof(mods), &needed))
{
    for (DWORD i = 0; i < needed / sizeof(HMODULE); i++)
    {
        MODULEINFO mi;
        if (!GetModuleInformation(GetCurrentProcess(), mods[i], &mi, sizeof(mi)))
            continue;

        DWORD base = (DWORD)mi.lpBaseOfDll;
        DWORD end = base + mi.SizeOfImage;

        if (eip >= base && eip < end)
        {
            char name[MAX_PATH];
            GetModuleFileNameA(mods[i], name, MAX_PATH);

            wsprintfA(buf, "%s @ %08X Size: %X\n", name, base, mi.SizeOfImage);
            Log::Write(buf);
            break;
        }
    }
}

Log::Write("====================================\n");
return EXCEPTION_EXECUTE_HANDLER;

}

And in DllMain I was adding the callback for the vectored exception handler:

AddVectoredExceptionHandler(0, CustomExceptionHandler);
