Invalid attribute arguments break the generator and cause multiple Roslyn service crashes in VS

[Rekkonnect]

The generator completely crashes when an invalid argument is provided in any of the generator-driven attributes. In my example, just a bad nameof panics the entire flow, with the following error dump on any of the internal error warnings in VS.

StreamJsonRpc.RemoteInvocationException: Index was outside the bounds of the array.

A quick example of a break:

    [Test]
    [MethodDataSource(nameof())]
    public async Task TestDocumentCharacterCount(
        DocumentCharacterCountTestCase testCase)
    {
    }

Does an empty nameof compile?

[Rekkonnect]

No, but it only yields an error without causing service crashes. When this is applied to any of the analyzed attributes, multiple Roslyn service crash warnings popup, text fizzles, and it seems impossible to recover without restarting VS.
