Unable to launch session with in uefn to playtest & load errors

Im not making a specific project
It doesnt matter what map im trying to launch a session for…even if its a new island template, im still not able to launch a session for it in fortnite
Either uefn or fortnite will crash or both will crash so that is really frustrating for me at the moment
Cause i usually live edit as i work on my projects…i think everyone does that and its really handy so itd be nice if i could find a fix to stop the crashes

And as for the load errors, are they really that normal at the moment? So its not a problem on my end then? Its an issue with uefn or fornite cause i failed to find a fix for them too?
