Strange, I was debugging my network connection lost issue so I created a new project.
Keeps in loading state for ever, then eventually crashes. (Loading into your Edit Session…)
I managed to join with my other laptop this session fine (other acc), and was able to actually start the session through UEFN (Start game button in UEFN).
The account which is connected to UEFN can’t seem to get in, tried multiple times to launch through UEFN again.
Workaround with private code works for me
