DotNetBenchmark throws reference assembly error-CodePudding

I want to test the performance of some methods using BenchmarkDotnet. Therefore, I downloaded the NuGet package added the usings and implemented it like this:

BenchmarkRunner.Run<SortingAlgorithmBenchmark>();

public class SortingAlgorithmBenchmark
{
    [Benchmark]
    public void BubbleSort()
    {
        SortingAlgorithms.BubbleSort(new[] {2,3,1});
    }
}

The BenchmarkRunner is in a console application which should show the output. Unfortunately the I keep getting this error: MSB3971: The reference assemblies for ".NETFramework,Version=v6.0" were not found. You might be using an older .NET SDK to target .NET 5.0 or higher

I don´t know where this error comes from since I never had a problem with the assembly references before and everything should be installed properly. At least I don´t know what could be wrong. Does anyone have an idea how to solve this problem. I run the program in VS 2022 and the TargetFramework is .Net 6.0

dotnet sdk folder

Microsoft.NET folder

According to the comments.

The solution to solve this question is to change the target to .Net Framework 4.5 .

It turned out that the problem was an unnecessary environment variable which pointed to the wrong sdk. After deleting the variable and restarting Visual Studio everything worked out fine.
