Summary
After updating to UEFN 35.00, I’m no longer able to reliably push changes to the game. Initially, launching a session works fine. However, once I make any changes to the map and try to push them, I get disconnected from the session. The log shows the following error:
LogNet: Error: UEngine::BroadcastNetworkFailure: FailureType = ConnectionTimeout, ErrorString = UNetConnection::Tick: Connection TIMED OUT.
Once disconnected, I must manually relaunch the session, which is time-consuming.
Additionally, when I try to push Verse changes, the update process gets stuck indefinitely. Verse compilation used to take less than a minute, but now it freezes and never completes — forcing me to restart the session again.
This issue makes it almost impossible to work efficiently in UEFN. These problems still persist even after the latest update.
Also after lunch session and close it UEFN want to push some files, and tahn again, start session and close it and UEFN want to delete them. What is going on?
2 logs attached. And screenshot of files that after session start and close deleted/created again and again.

What Type of Bug are you experiencing?
Verse
Steps to Reproduce
-
Open a project in UEFN 35.00.
-
Launch a live session — it starts successfully.
-
Make any changes to the map (e.g., add or move actors).
-
Try to push the changes to the game.
-
Observe disconnection and timeout error in logs.
-
Relaunch session.
-
Make changes in Verse and try to push them.
-
Observe that the Verse update hangs indefinitely with update session status in UEFN.
Expected Result
- Changes to the map and Verse code should push to the live session without disconnection or long delays like it was before.
2.. Verse compilation should complete within a reasonable time (~1 minute as before).
Observed Result
-
Pushing map changes disconnects me from the session with a Connection TIMED OUT error.
-
Pushing Verse changes causes an indefinite hang, requiring a full session restart.
-
Workflow becomes extremely slow and unstable.
