I've also been experiencing this issue for the past few days. Cannot export docs in Markdown (single page or all pages), but HTML and PDF worked for me. I tried in Safari, Chrome, and Brave on both my old laptop and my new laptop. Both laptops are MacBook Pro, the old one running 11.1 (Big Sur) and the new one is still on 10.15.7 (Catalina).
