Vst3 problem - TypeLoadException

Hey I want to use the brandnew VL.Audio.VST.

But there is a TypeLoadException in my case:

I have installed a lot of vst-plugins - hopefully there are no cross-references or something which let not load the VL.Core.Commands.IHasCommands.
here are no cross-references
Does anyone have the same problem?
I have the newest version of VL.Core.Commands and .net frameworks installed and I use VvvvGamma 6.6.

Also something strange happens when the error appears:
Cannot open the help menu and the settings-menue in the top-right corner anymore…?

thanks for the audience

you should use one of the latest previews.
use gammalauncher to make it easy to install and manage various versions.

Hey, thanks for reply.
I tried to install different pre versions of 6.7 but in my case there is a problem with all of them:

So I cannot work with this pre-versions for now.

is it a problem of the OS → Win10

VST needs latest 6.7 preview. The error you posted doesn’t look like VST related at all - system is having issues creating the Direct3D11 device for the patch editor. Apart from VST, does 6.6 stable work normally for you?

Yes, 6.6 works normally so far. No Problems.
On my other PC 6.7 works fine - also VST.
It seems I have the same problem with the latest version of Gamma Launcher. Version 5.2.2 works fine

I think I have to create a new topic for that.
The solution for this topic was to install the pre-version 6.7 of Vvvv!
Thx
