The 'DotvvmSubTypePackage" package did not load correctly

Hi, I got the error the package did not load correctly on Visual Studio 2022.
Please check it. Thanks!

I’m having the same error, also in VS 2022.
The tool does nothing. :frowning:

This most likely happens because the DotVVM extension isn’t compatible with the specific VS version, last update should support Visual Studio 17.9.4 or 17.10.0 Preview 2.0 (Release notes | DotVVM Documentation). Unfortunately, Microsoft is constantly breaking the VS extension API, sometimes even across patch versions, without any heads up to extension developers.

Can you please try downgrading? If that doesn’t help, please post the mentioned ActivityLog.xml file, or just the last exception(s) from this file
