Hello,

I’m sure this is probably a dumb question. I’m on day two of trying to fix it so I’m probably (definitely) frustrating myself into making it more complicated than it is.

I looked up solutions online and they all recommended different files(?) on the installer which are all out of date now / not supported anymore so I’m not sure which to use.

I’m trying to add c++ and getting an error. I tried making a game as c++ and as blueprint and same result each time

Any help is really appreciated! Thank you

I have the same error. Its something to do with Nuget not being compatible with the .net 8 target.

I’ve hit this issue for the last few days and I was able to fix it but I don’t really have a lot reason why it might have happened. What I ended up doing is deleted this folder “C:\Program Files\Epic Games\UE_5.6\Engine\Source” then in the launcher I clicked to verify the install so it redownloaded that folder. Then I went to my projects, deleted all the cache and solution, regenerated the VS project, and it built fine after that.

This may or may not matter but it will complain about nuget packages. I chose not to update all, only the ImageMagick one with the vulnerability and specifically the 14.8.1 release and not the newest. I was desperate to fix this so I was being pretty cautious.

My thought on the issues might have been some sort of windows update mixed with a 5.6.1 update. Multiple people on my team had issues and I was even able to break it on my personal computer. I couldn’t make a brand new project and have it complete. 5.7 even had issues for me and I did the same to fix.
