App hangs at RNFS.exists()

I have the following code:

```
const exists = await RNFS.exists(dest);
debugger;
```

On iOS, everything works as expected. On Android, _sometimes_ everything works as expected, and _sometimes_ (completely randomly, seemingly not correlated with any event or pattern) it just hangs there forever. I don't get to hit the debugger and none of the code afterwards is run.

The whole code is inside a try/catch block and I've got a debugger inside catch too, and it's not being hit as well.

What am I doing wrong?
