I've disabled the failing tests in #66248, reopening to track the issue.

Is there a known workaround for this bug?

I get the same exception as described when calling JsonSerializer.Serialize and I'm stuck with .NET Framework at the moment because I'm writing a VS 2019 extension.

Adding <PackageReference Include="System.Runtime.CompilerServices.Unsafe" Version="4.5.3"/> to my .csproj doesn't help, as I also get a System.IO.FileLoadException when I call JsonSerializer.Deserialize, but with version 6.0.0.0.

System.IO.FileLoadException: 'Could not load file or assembly 'System.Runtime.CompilerServices.Unsafe, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. [...]
