Hey, thanks for the report. This is a known bug. The combination of interface{} (curly braces) plus backtick struct tags with spaces can trigger a hang when rendering markdown.
The same issue is already documented here: Markdown Preview causes "Cursor Helper (Renderer)" to spike to 100% CPU and crash
The team is aware, but there’s no ETA yet. Your report helps with prioritization.
For now, the workaround is to use any instead of interface{} in Go code. Without the curly braces, it doesn’t crash, so this should unblock you.
Let me know if you run into anything else.
