“Generate Visual Studio Project Files“ broke for no apparent reason.

This is UE4.26, it was working fine yesterday and one system restart later it’s not working.

I can still open the project’s solution files, and rebuild my project just fine, I can package it too. But trying to generate VS files doesn’t work.

This is the error I get:

Building UnrealBuildTool in C:/Unreal Engine/UE_4.26…
Running: C:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe /nologo /verbosity:quiet “C:/Unreal Engine/UE_4.26/Engine/Source/Programs/UnrealBuildTool/UnrealBuildTool.csproj” /property:Configuration=Development /property:Platform=AnyCPU
Missing C:/Unreal Engine/UE_4.26/Engine/Binaries/DotNET/UnrealBuildTool/UnrealBuildTool.exe after build

  • I have tried verifying the engine through the Epic Launcher.

  • I am able to successfully package the project.

  • I know that my VS installation is fine because I just finished trying to rebuild the project.

  • UnrealBuildTool.exe is not located inside a separate “UnrealBuildTool“ folder, it is located in “DotNET” folder. It’s trying to search in the wrong folder…

Does anyone happen to know what broke?
