I have the same issue, so maybe my mod list might help narrow it down? I didn't grab the crash log since right now I just only activate it if i was to do a downfall run. I put dashes in front of mods that I know I didn't have activated when I first saw this crash. :) Good luck with figuring it out!

Downfall

I have also problem with crashes after last gremlins update. In my mode list I saw that Downfall 3.1 is no longer 100% compatible with Infinite Spire mode. Without Infinite Spire everything working perfect, but with Infinite Spire I can't play The Snecko and have also some problems with The Champ. Bufore last downfall update everything worka perfect.
