TTS bug

[janjanusek]

Hello, I'm using your TTS library and must say it's very good, but I have no idea why when I instantiate OfflineTts model and run generate it returns result, but when I do it second time on the same instance I'll get error, for model I'm using this

new OfflineTtsModelConfig()
        {
            Vits = new OfflineTtsVitsModelConfig()
            {
                Tokens = Description.Tokens.FullName,
                Model = Description.OnnxModel.FullName,
                DataDir = Description.NgDataDir.FullName,
                NoiseScale = 0,
                NoiseScaleW = 0
            },
            Provider = "cpu",
            NumThreads = 1,
            Debug = 1
        },
        MaxNumSentences = 1
    }

I'm using org.k2fsa.sherpa.onnx package and tried all possible versions, also alongside I'm using as referrence within my project onnx runtime (for my other models) but that should not affect this package. My app is running on NET8, and I'm using Win11 with EU based lang.

error I'm getting on second run for any input (even the same one):

worth to notice that when I create another instance it works again for single use..
