vstest.console fails to connect when using any NUnit version below 4

[Hertzole]

Describe the bug
I try to run stryker on my project and it always failed when trying to connect to the vstest.console. Currently my project is using NUnit 3.14.0 (woo, I just love supporting unity...) and then it fails. However, if I upgrade just a step to NUnit 4.0.1, it works just fine. But I can't use 4.0.1 because my library needs to test against older .NET versions.

Expected behavior
I expect stryker to run without issues even if I'm using NUnit 3.14.0.

Desktop (please complete the following information):

• OS: Linux (Manjaro Arch)
• Type of project: Core
• Framework Version: .NET Standard 2.0, .NET Standard 2.1, .NETCoreApp3.1, .NET 5, .NET 6, .NET 8
• Stryker Version 4.5.1

Additional context
These are the (what I think is) relevant packages I have installed for testing.

<PackageReference Include="Microsoft.NET.Test.Sdk" Version="17.1.0"/>
<PackageReference Include="NUnit" Version="3.14.0" />
<PackageReference Include="NUnit3TestAdapter" Version="5.0.0"/>
<PackageReference Include="NUnit.Analyzers" Version="3.3.0"/>

Hello
Could you please try running VsTest on your test project from the CLI and see what happens ?

This error js a hint that VsTest fails during initialization. Stryker cannot get any more details than this.

Running dotnet vstest on my built dll files works just fine, as well as just running dotnet test.
