NuGet packages when I try to build

[Arbifoxx]

Error: NuGet packages need to be restored before building. NuGet MSBuild targets are missing and are needed for building. The NuGet MSBuild targets are generated when the NuGet packages are restored. (SRCubeSlimeMod)

ok I solved it but now Im getting this: /usr/local/share/dotnet/sdk/5.0.100/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.TargetFrameworkInference.targets(5,5): Error MSB4186: Invalid static method invocation syntax: "[MSBuild]::GetTargetFrameworkIdentifier('$(TargetFramework)')". Method '[MSBuild]::GetTargetFrameworkIdentifier' not found. Static method invocation should be of the form: $([FullTypeName]::Method()), e.g. $([System.IO.Path]::Combine(a, b)). Check that all parameters are defined, are of the correct type, and are specified in the right order. (MSB4186) (SRCubeSlimeMod)
