MacAndPaints

Hey all, so I was going to open an APNG file with Simon Brown's APNG plugin, which has worked historically (and I have not updated Paint.NET since the last time it has worked). Here is the crash log. I've tried reinstalling the plugin, as well as Paint.NET, but have had no results. A quick scan on the pinned post shows no "obvious" fixes. Any help would be appreciated, thanks!
