Update: AppleScripting isn't supported in the first beta of Monterey, hence the errors.

This issue appears to have been fixed on Monterey Beta 3. You have to add the .inlineOnlyPreservingWhitespace option when initialising the AttributedString. struct MarkdownTest: View {     let attrStr = try! AttributedString(markdown: "Hello **World**!\n[This is a link](www.google.com)", options: AttributedString.MarkdownParsingOptions(interpretedSyntax: .inlineOnlyPreservingWhitespace))     var body: some View {         Text(attrStr)             .padding()     } }
