I have found a #Typora beta installer from somewhere around late 2018 in my downloads. Back from when it still had a beautiful icon, you know. :)

Reinstalled it. And it works. 🔥

Maybe it lacks some shiny features (it's a five year old beta, after all), but I use it mainly for writing prose, so it doesn't matter much.

Thank myself for being such a hoarder. 😆
