Server Travel doesn't Work when I packaged

Edit: Non-Seamless ServerTravel is what is currently broken in UE5. Seamless ServerTravel does seem to work, but it’s not compatible with our game specifically.

If you are UE5, the command “servertravel” seems to be 100% broken currently for packaged games, I can’t speak to anything with only the Editor.
Our game is 4 years in development (Blueprints only); have never had an issue with servertravel.
Now, in our packaged game, the command no longer lets clients re-connect. They permanently drop. This isn’t even using our game code, this is just simply typing in “ServerTravel MapName?listen”, have also just tried “ServerTravel MapName”. Server travels fine, but now as of UE5, clients will never reconnect.
