Unable to cast object of type 'Avalonia.Media.Color' to type 'Avalonia.Media.IBrush'.

When I modify the variables in the Binding, if there is codeBlock content, an error will occur and the Markdown content will not be rendered.
ContentString like this:

` ` `
a
` ` `

Error:

[Binding]An error occurred binding 'Markdown' to 'ContentString' at 'ContentString': 'Unable to cast object of type 'Avalonia.Media.Color' to type 'Avalonia.Media.IBrush'.' (MarkdownScrollViewer #40133923)

Code:

<md:MarkdownScrollViewer 
                Markdown="{Binding ContentString}"
                Margin="5"
                MaxWidth="1000"/>
