I'll be honest, this looks like it has nothing to do with us. If it's the same issue you've been having, you may want to see about reporting this to GildedGames for Aether, cause every block that's showing in your log as trying to update are all Skyroot doors from Aether. See if they have anything to say, cause I have a hunch that its Aether. See if removing Aether does anything first though.

The cause of the crash is Aether. The VanillaFix message is telling you about a bug that caused mod identification to error.
