Does nothing shows up in notification when you press export at all? I checked in 1.13.2 and found no problem. Also I bring 1.13.1 back in the download page.
So it still happens in 1.13.2 BUT it works in 1.13.3. I can't tell what I did different with my setup but I am able to export png files with ease now. Thank you for such an awesome tool. I love seeing the updates on twitter.
