UE5 server travel crashes

Calling “servertravel (worldname)” in console commands (blueprint) in UE4 doesnt travel in the editor, and works perfectly when packaged, however when called in UE5 it will crash with an exception access violation regardless if its packaged or not. Is this a known issue? Is there some alt server travel method im supposed to use?

I am facing the same issue, the logs aren’t helpful at all - servertravel works fine in UE4 for both seamlesstravel in packaged, and plain servertarvel in Editor, but none of the same methods work in UE5. This is all I am getting in the log

This is a big issue. Any fix out there?
