### Summary I made a small update on my island and since 38.10 i get this error message everytime i want to Launch Memory Calculation. I did restart UEFN, i waited 2h, I even waited 12h today tp try it again and same error. I get Parallel upload flow is already running first and then i get the Internal error after. ### Please select what you are reporting on: Unreal Editor for Fortnite ### What Type of Bug are you experiencing? Publishing ### Steps to Reproduce Launch session in Edit. Going back to UEFN and click on Launch Memory Calculation. And the error happens. I get Parallel upload flow is already running first and then i get the Internal error after. ### Expected Result No errors like usual and i can continue in Creator Portal to publish my map. ### Observed Result See the screenshot i posted. ### Platform(s) Windows ### Island Code 6005-4587-3961 ### Upload an image ![Screenshot 2025-11-12 145137.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/1/9/d/19d885fbfe1e060e0bc2b0c51d56bc136d6cde1c.png) ![Screenshot 2025-11-12 145124.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/d/4/a/d4abc9f7b8c4ed69e96b9c0b03225b108048b39d.png) ### Additional Notes I did a Fixed Validation Issue, an Update Redirector Reference, a Project Validation first and every time and i still have the same issue. I also removed the Island Settings and added a fresh one with the same settings because i had a previous bug related to that issue. ---

I am also getting this issue but only specifically on one map and i tried everything and cant seem to fix it. At some point it mentioned an error about localization which i found out its the language files, but even running auto localization didnt fix the issue. ---

Got this error a few times this morning. I hadn’t noticed the “Build Localization” checkbox on the private version upload menu before today so I assume that could be the cause. First thing I did was close everything and restart the pc. Second, I went into my project settings and disabled all of the language localization settings just to see what would happen and immediately the next memory calculation was successful. ![Screenshot (14222)](https://d3kjluh73b9h9o.cloudfront.net/original/4X/9/a/a/9aa17c6cc9a7578a3ea911e39d765332c618c571.png) ---

I haven’t made use of localization or translation in the map I tested this on so I have no idea if it will affect any translated materials. You might have to duplicate your project and do some testing for that. ---

So i got the error also in my other project, and it was the localization for this file that gave me the error zh-Hans/HIDEnSEEk.po So i removed all the localization manually in my computer, redid it just for English and French, had to restart UEFN and now was able to published, will try again in my previous project. ---

Well, i did the exact same steps for my previous project and still got the same errors. This is what the AI said about my issue @epic , if that helps “UEFN publish fails with ‘Parallel upload flow is already running’ and ‘Internal error’ due to a stuck Valkyrie backend process (module ID: abe69457-42a0-27f0-302d-5db05b39a738), blocking new builds despite clean localization and project state.” ---

@Bug-Reporter Any update??? Because my previous map i still can’t upload it and even any new map i make i also can’t upload… so at that point it feels pointless to work on Fortnite maps if we can’t publish them… a bit frustrating!!! ---
