I’m still having the same issue even after this update is there anyway to fix this?

The same on my project, this new update didn’t resolve anything , still the same UEFN crash on session launch without any clear reason,

Why not we can revert to old version before v 29.0 update available until most users confirm its working ok, after all its not normal to release an update without extensive beta testing for some time from many users.

UEFN is starting to be a very frustrating and unstable platform, it will be useless to wast time searching for solutions for problems we don’t know. :unamused:

Can someone please fix this?? it’s been almost 4 weeks I can NOT work on my projects without asking someone to launch a session for me
