Can’t launch a UEFN session due to Verse errors (Verse Build Diagnostics Error). Doing this in multiple maps, rebuilding verse code don’t fix it.

Experiencing the same thing now. Noticed I had errors when I opened the project that didn’t exist before, made some changes and it builds. Go to launch and get the same exact error as you.
EDIT: I was able to cheese this into working, When I looked at the build error in the log in my case I was using SetMesh with a mesh I have using Verse assets. For whatever reason mesh’s need "_asset " appended to them when they didnt need this yesterday?? Anyway after adding that to each line in my Verse script that has a reference to a mesh I could build, But on launch still had issues. I found it was saying that there was an issue with a script located in:
Fortnite Projects\mymap\Plugins\mymap\sys\versions\123\Content
I opened the .verse for my script there and added _asset to each line like I did in my script in the IDE, saved, and relaunched and it worked.
For you I would navigate to the \sys\versions###\Content folder and just check that the scripts there match what you have in the IDE and if not make the changes and relaunch the session.
Edit: Looks like also for some projects Scene Graph is getting enabled by default and causing issues. There is a post that shows how to disable it again, But I don’t know what kind of issues this will cause later on.
Seems to be fixed!
