Console Errors on startup

vvvv gamma question
1

After last day´s save i can not open the project i was working on for weeks.

I am using a startup command to start vvvv and open the patch:
start "" "%dir%Gamma\vvvv_gamma_7.4-win-x64\vvvv.exe" --nuget-path "%dir%Gamma\nugets" --open "%dir%%patch%" -m --log

The patch starts fine though when i open vvvv first (without the --openargument )
and drag the patch into the editor afterwards.

Can anyone spot something obvious in these prints?
I did not change anything crazy or added any new dependencies since the last save.

Console error, editor frozen, nodes grayed out:

Can you zip the project and send it to us?

Since i could still export the app just fine i went with the manual editor startup to finish the project.

I have now dug deeper and noticed that i had set a file dependency to vl.stride.runtime.dll earlier in the project. I have set it to be able to use one of the internal nodes that are not in the node browser. Somehow this dependency also was there twice now. Anyway removing it completely solves the startup issue but also removes the one node i need. I wonder if there is a better/correct way to get any of these “hidden” nodes without referencing this DLL like this.

PR it to VL.StandardLibs or via some intermediate c# project or patch…

In this specific case you can reference the VL.Stride.Runtime nuget package, then add the IsFriend attribute and set it to true using a texteditor. (Remove the reference to the dll)


<NugetDependency Id="RhMStr7gg2eOyC9x59LL8e" Location="VL.Stride.Runtime" IsFriend="true" Version="2025.7.4" />

Not sure if it will “fix” the crash though.

@devvvvs please consider documenting this feature and ideally add a way to enable it in the UI. It comes up regularly. Imho not expsoing it causes more inconvenience than it prevents.

This is already being worked on as reference management gets moved to new UI.
