Program crashes after trying to render as gif

I downloaded the windows 64 bit version from https://www.synfig.org/ and made a test animation that it’d like to export as a gif. After choosing the gif extension and pressing render synfig freezes and crashes. Export as png does work but it’s a hassle to then convert those images to gif if it can be done by the program. The file size I’m trying to render is 1280x720, duration of the animation is 45 frames.

Render as ffmpeg doesn’t work either: synfig says it rendered successfully but the file doesn’t show up in the designated folder.
