These errors can appear for a number of different reasons and are likely different for each user. As many users have commented above this is error is essentially saying that the cloud cooks are failing for a particular reason. Recently we made a change that affects how materials are compiled that disallows certain mat functions and nodes that aren’t supported on all platforms. You should be able to find more information on the particular error in the message/output logs. Please ping me if you need any further help/insight/clarification.
Our team had the same issue but thanks to HalcyonKnight96, now the project is working.
Our problem was the Distance Field thing. I added Feature Level Switch node not to use some nodes related to Distance Field in ES3_1.
We realy need help, we are an independent studio and we just stopped working on our original IP to invest our resources in UEFN as a bet, but we are getting very frustrated with the lack of information. We are working on this issue for a month and for many times we are able to launch session again by removing stuff, but it looks completly random, later the errors come back or it just hapen to some team members. Can you point a direction ? We need to finish this project.

----------------------------------------- Sharing to help someone with the same problem. For someone it could maybe be the only problem but looks like i have any other.
By removing this node i could launch once, but the problem came back again.
So i am updating the problem with the last JOB_ID:

@HalcyonKnight96 Also running into a cook error. However, I tried restarting UEFN and now the project crashes every time I open it. If anyone could point me in the right direction that would be great. This was right after adding a lot of accolades and tracker devices to my island.
SOLVED:
The issue was caused by calling “EliminationManager.EliminationEvent.Subscribe()” inside of a block expression.
I’m having an issue where I check my project size it gives me an error which it tells to check on output log. When I do it gives me this " Content (re)cook error errors.com.epicgames.cookplugin.materialerror.
JOB_ID=073e5971-8f8b-4285-ad5d-ad0bb6f53441" how do I fix this?

Thanks for every help !
Hey there, looking for some assistance with my error. I am not seeing anything in the message log other than some niagara files that are not being found since the latest update? In any case, I was really hoping you could help me get past this, it’s giving me a moderation warning as a result and I haven’t been able to launch a session. Thanks a ton!!
