Why multi-level pointer dereferences crash external tools:

When a player disconnects or enters network cull range, intermediate pointer addresses become null or point to unmapped virtual memory pages.

Safe Pointer Dereferencing Routine:

template<typename T>
bool SafeRead(uint64_t address, T& outVal) {
    if (address < 0x10000 || address > 0x7FFFFFFFFFFF) return false;
    SIZE_T bytesRead = 0;
    if (!ReadProcessMemory(hProc, (LPCVOID)address, &outVal, sizeof(T), &bytesRead) || bytesRead != sizeof(T)) {
        return false;
    }
    return true;
}

Checking 0x10000 < address < 0x7FFFFFFFFFFF eliminates 99% of null dereference access violations.

Clean and robust memory reading.
