Here is my setup:

<Project Sdk="Microsoft.NET.Sdk">

    <PropertyGroup>
        <TargetFramework>net6.0</TargetFramework>

    </PropertyGroup>

    </ItemGroup>

    <ItemGroup>
      <ProjectReference Include="..\MyProject.csproj" />
    </ItemGroup>

</Project>

Here is the task setup:

When running, half time it succedes, other times it gets stuck for hours.

This started happening when I switched from dotnet 5 to 6.

Tests are working fine when executed on developer machine.

Ok seems like adding that solved my problem:

    <ItemGroup>
      <None Update="xunit.runner.json">
        <CopyToOutputDirectory>Always</CopyToOutputDirectory>
      </None>
    </ItemGroup>

xunit.runner.json

{
    "parallelizeTestCollections": false,
    "maxParallelThreads": -1
}
