hello?

I don't see any errors related to Deco in the log. Have you tried a binary search of your mods (disable half of your mods, load world, if crash occurs disable half of the active mods; if no crash then try the other half) to confirm that Deco is the cause? There's a lot of other errors and warnings in that log.
