Testing version: 2.0 10209
What were you doing: Exporting all notes to markdown + attachment (other options unchecked)
What happened: Crash of app. Exported are only some attachments. Export without attachments (to markdown) works without problems. I was not able to identify precisely exporting what note (what type of attachment) caused the issue.
If you want crash info (report), let me know, I would DM it to you.
