### Summary

In UEFN pushing changes or when launching memory calculation I receive a “Network Connection Lost” error message (inside the Fortnite client).

### Steps to Reproduce

1. Open project in UEFN and click Launch Session. This is successful and the Fortnite client connects and is playable.
2. In UEFN Launch Memory Calculation (after stopping the game in Fortnite if not already done).
3. Private Island upload appears successful and Fortnite client begins connecting.
4. The connection fails.

### Expected Result

When pushing changes or launching memory calculation in UEFN the Fortnite client should connect successfully and be able to run the memory calculation.

### Observed Result

Fortnite client displays an error message:

```

### Platform(s)

windows

### Island Code

7154-1898-4800

### Additional Notes

Followed the same steps in an empty project (including adding a few props to push changes) and it was successful. So the issue is specific to this project.

This workaround worked for me:

> [@Memory Calculation - Editor keeps disconnecting](https://forums.unrealengine.com/t/memory-calculation-editor-keeps-disconnecting/1298808/10):
