I’m adding an update because the issue of UEFN being unable to start a session has recurred.
・I previously mentioned that UEFN was able to start a session after I updated my graphics card drivers, but unfortunately, UEFN is now unable to start a session again.
・Following that, I reinstalled both UEFN and Fortnite. This allowed UEFN to start a session once, but the problem has since returned, and UEFN is again unable to start a session.
・It’s worth noting that I’m currently still able to start the game using a private code in my environment.
