Summary
UEFN pushed/Edit Sessions are showing recurring network instability during editor-launched sessions. The issue appears as packet loss, the in-game Wi-Fi/network warning icon, freezes, and occasional disconnects from the editor session.
This does not appear to be caused by a specific island/project, because I reproduced the same instability in a separate blank UEFN project with no custom gameplay, no player-input test requirements, and minimal/no content. Normal Fortnite gameplay on the same PC/network is stable after configuration, with no comparable packet loss or disconnect behavior observed.
Normal Fortnite gameplay on the same PC/network is stable after configuration, including 120 FPS gameplay without packet loss, so the issue appears specific to UEFN pushed/Edit Sessions rather than general Fortnite connectivity.

Steps to Reproduce
- Open UEFN on Windows PC.
- Create or open a blank/default UEFN project.
- Launch or push an Edit Session from UEFN.
- Join the session in Fortnite.
- Remain in the session without requiring gameplay input.
- Observe network stability over the session.
Expected Result
A blank/default UEFN pushed/Edit Session should remain connected and stable, with no recurring packet loss, Wi-Fi/network warning icon, freezes, or editor-session disconnects.
Observed Result
The UEFN pushed/Edit Session shows intermittent network instability even in a blank/default project. Symptoms include packet loss, Wi-Fi/network warning icon, freezes, and occasional disconnect behavior. The same class of issue also occurs in a separate non-blank UEFN project, but the blank-project reproduction suggests the issue is not project-specific.

Additional Notes
I am intentionally reporting this using a blank/default UEFN project as the reproduction case to avoid project-specific variables.
