UEFN Cook Error when Launching

I just confirmed that in my case it was caused by deleting assets that were referenced somewhere and that reference remained there. The fix is to clean up all the references left after deleting assets.

any tips on checking that? I’ve deleted what I think is everything connected, but its not working out

Thanks all, we’re continuing to investigate.

i have the same issue in my rocket racing map when i do a normal long track and start session i get edit mode error and content cook failure any help please i deleted my map two time and do it agein and still have the same issue.

I started getting this a few hours ago, I was able to cook my map fine this morning, now I need to go back to my versions before the last update where all the assets were tweaked upon opening the map in order to build it again. The bug seems to be coming from an issue caused by that process. The exact same URC version that worked this morning no longer works.
