MSbuild errors gamma 2021.3.3

[jib]

Hi, I’m trying to revive an old project made with gamma 2021.3.3 but got these errors

Is there a way to fix it ?
Also Windows version is changed from 10 to 11… is that why the errors occur ??

If I open the same project with gamma 5.2 these errors do not appear but I’d have other problems instead (I’ve created another post for that)

Thanks in advanced!

Try installing MSBuild and the .NET 6 SDK or run the installer of that older vvvv version.
