Reproduction here: https://github.com/thomhurst/TUnit/tree/2e5d965e1be32bb87dcc6e0b39f845be2af89b53

Run the tests inside MarkMethodStaticSuppressorTests.cs

The following exception is thrown:

 System.TypeInitializationException : The type initializer for 'Microsoft.CodeAnalysis.Testing.Lightup.ProgrammaticSuppressionInfoWrapper' threw an exception.
  ----> System.InvalidOperationException : Property 'System.Collections.Immutable.ImmutableArray`1[Microsoft.CodeAnalysis.Diagnostics.Suppression] Suppressions' produces a value of type 'System.Collections.Immutable.ImmutableArray`1[Microsoft.CodeAnalysis.Diagnostics.Suppression]', which is not assignable to type 'System.Collections.Immutable.ImmutableHashSet`1[System.ValueTuple`2[System.String,Microsoft.CodeAnalysis.LocalizableString]]'

Looks to be code in roslyn-anlayzers. That is not roslyn: https://github.com/dotnet/roslyn-sdk/blob/e5ac2973139bde52fae4f85327ea7ac7bc5eedf6/src/Microsoft.CodeAnalysis.Testing/Microsoft.CodeAnalysis.Analyzer.Testing/Lightup/ProgrammaticSuppressionInfoWrapper.cs#L11
