[The_Jorrick27]

Hey I cant create C++ projects anymore, nor compile C++ components added to blueprint projects.

In my IDEA when I try to compile my project:

Greetings @The_Jorrick27! Let’s see what we can do here.

Checking your error log and screenshots, the first step (which I’m sure you already covered) would be to ensure that you are using the latest build and updates for UE, Visual Studio, and your OS.

After that, your issue has been tackled on other threads in the community, with different solutions, either disabling settings in Rider as seen here, or switching your Visual current version to an older one.

You can check both threads here, hope this helps!

So I have the same setup on my laptop and everything works fine… Same IDE , same unreal version etc… Because of that I wiped my PC and reinstalled everything from scratch . Same issue =/

So it isn’t rider related…

now that i uninstalled it and only have Visual Studio 2022 installed it still shows the following error when attempting to create a new C++ project.

The project could not be compiled. Would you like to open it in None?

Visual Studio 2022 has some banned components in UE5.5… you must update them to the required versions.

Alright so I now fixed it … Installing windows SDK manually, updating windows, repairing visual studio and
copying “C:\Program Files\Epic Games\UE_5.5\Engine\Binaries\ThirdParty\DotNet\8.0.300\win-x64\host\fxr\8.0.5\hostfxr.dll” to C:\Program Files\Epic Games\UE_5.5\Engine\Binaries\DotNET" seemed to fix it… I don’t know what exactly fixed it there but at least i can create a new C++ project now ^^ Thx for the help =)

[Ivan3z]

You really just had to go to the Visual Studio installer and uninstall version 14.42.34435 and then install version 14.38.33130

[The_Jorrick27]

Ah, okay … Yeah sorry am new to working on big projects. I know how to code but that’ more or less it xD

[Ivan3z]

You just need to read the log messages carefully… That helps a lot!!
Best Regards!!
