Cannot access a disposed object

Description

I get an exception when I use HostBuilder in Unit Tests under debug.

System.ObjectDisposedException: Cannot access a disposed object.
Object name: 'System.Threading.ThreadLocal`1[[System.Collections.Concurrent.ConcurrentBag`1+WorkStealingQueue[[MonoMod.Core.Platforms.Memory.PagedMemoryAllocator+Page, 0Harmony, Version=2.3.3.0, Culture=neutral, PublicKeyToken=null]], System.Collections.Concurrent, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a]]'.

I have no idea why that exception happened. And I don't know how to provide any details.

What runtime are you on? When are you seeing this exception? I would expect it to only happen on shutdown, but AFAIK only .NET Framework (and maybe Mono) actually tries to run all finalizers on shutdown.

.NET8+Windows

The exception occurs when I call HostBuilder.Build() in debug session in unit test xunit + allure.xunit (2.12.0)
I created a corresponding issue for Allure allure-framework/allure-csharp#500
