Native backend doesn't capture out-of-memory errors

When using the `native` backend on Windows/Linux out-of-memory (OOM) crashes are not captured in Unreal Engine environment.

Steps to reproduce:

```cpp
// Trigger OOM by allocating memory in a loop until exhaustion
size_t Count = 1024;
while (true)
{
    void* _ = malloc(Count);
    Count *= 2;
}
```
