Hi. I really need help with this one, otherwise I will lose 100+ hours of work…

Whenever I try and load into a Playtest session it won’t load the map and just gives me this error.

When I load a UEFN session, it allows me to stay in the session for around 10-20 minutes and then gives me another network error.

I have tried everything, removing recently added assets, restarting everything.
This is what the Output Log says and I don’t understand what it means.

I tried other maps as well and they work fine. Just this one I have been actively working on, this has happened since yesterday.

If anyone knows how to fix this it would be REALLLY appreciated! Please.

One thing that MIGHT be causing this error is I have a lot of classes and maps being stored persistently in a weak_map. Would this cause the error?

We have the same issue. I was told that Epic is looking into this, definitely make a ticket in issues and post your logs as well, so we can have one more case if asked (press “report issue” in UEFN as soon as it gives you the network error.
