After downloading update 23.10 I cannot launch the live editor and am met with this error.
Project was launching ok before the update.

Hey @Cardin, thanks for letting us know. Out of curiosity were you doing anything unique in your workflow before this error occurred? For example were you dragging assets from the full Unreal Engine/Editor into UEFN? Or did this simply start occurring after the last UEFN update? Any additional information would be much appreciated! Thanks!
Correct, it started happening after the update with no changes to the project.
There are quite a few assets pulled in via UE, some engine content as well as assets from the store.
These were all working prior to the update however.
I did see a list of disallowed objects on the first cook after the update, the login server is down right now but I will update this post ASAP with the list.
May not even be the issue but here are all the disallowed object types.
I cannot confirm if these errors existed prior to 23.10.

I’m also getting the same issue now. In my case, I’ve only been working in verse so I haven’t been adding or moving anything into the editor. I was originally testing a verse script in-game and needed to push changes to update the script only for the cook error to occur.
I’ll also provide my logs:

Hey @Cardin and @jstKamui. So the issue “No output file found” is similar between your issues but the reason is not. What we have is 3 separate issues I think:
The error.json output file has been messed up and that’s why you’re not getting an output file. This is a known issue and we’re working on a fix.
@Cardin issue: Points to some texture data that’s gone missing? Still investigating.
TLDR: Issue with error.json is causing different issues to look the same.
EDIT: @jstKamui if you’ve been adding map-related Verse content perhaps consider removing or commenting out those sections for now. I’m not aware of a workaround but I’ll try to find one.
Thankyou @HalcyonKnight96 for narrowing it down to the landscape.
Upon exporting, deleting and re-importing the landscape I noticed I only had 4 LandscapeStreamingProxies so I think I had duplicate landscapes from early on in the project.
Restoring the landscape was actually not as difficult as I thought it might be, here are the steps if anybody else needs to export/import landscapes.
I exported the heightmap file as well as all the custom layer data in Landscape>Manage>Import (Export is in Import, click the radio button)
After deleting the landscape I just re-imported the heightmap and layer data and used the same landscape material, if you are not using custom landscape materials, leave the material as default.
@Cardin glad to hear it wasn’t super painful to remake your landscape. I’ll keep an eye on this issue in the future and if it pops up again we’ll investigate more deeply. Thanks!
Had something similar happen today. After checking out a few posts on the forums I tried saving all the landscape actors via the outline by selecting them and right clicking save selected actors. This seemed to have fixed my cook warnings and solved my issue.
Im not sure if complety related but I had this same error code when trying to launch after adding the Beacon fron the devices folder. Removed it and no errors.
