Hi @RealLawyerJoe . Please reply to the thread with the island number and the project ID, as Epic Support requires these details to investigate the issue. If you make a private version, do you get the same problem? Could you try to verify your installation, because sometimes the updating system gets corrupt and you have to uninstall 37.\*\* and fully install 38.00 To verify, follow the post [How to verify UEFN/Fortnite](https://forums.unrealengine.com/t/urc-exe-and-urc-dll-get-flagged-as-malware-from-microsoft-defender/1802519/5) ---

Yes, if I make a private version I still get the error. island code is 7761-0247-8214 Project ID is: “9c50e971-46b0-bc0c-51b8-df941222316b” Edit: I should add the fact that this is the ONLY project this happens in, I had been working on something different. Came back to this project to update it and now its entirely broken and gives me that error. ---

hi @RealLawyerJoe This does happen a lot because the [UEFN - Content Service](https://content-service.bfda.live.use1a.on.epicgames.com/#/all-projects/@personal) has become corrupted in the previous version. When you make a new project, you make a new entry on the content service, and of course, that is where you store your Persistent data. It should be possible to delete all the data and recreate it. ---

@RealLawyerJoe , Well must be something special in migration. The error message is wrong as the end line is a cooking error in one of the assets. Who knows how you find that!? Sorry, ran out of ideas. You have probably run Asset Validation and not got any errors locally. ---

I havent gotten any errors at all! This error only pops up AFTER ive run a memory calc, it doesnt even show up in logs or the output log. I wish someone from Epic could step in here cause this is really frustrating ---
