The error in the full log is different from the error you provided in the other post…

If you have the decorations mod, try removing that. It is a common cause of this issue.

i fixed the log inconsitancies

Hm… I can’t see any specific mod to blame here…

This is a bit hard to pinpoint by just looking at the logs.

The why it talks about air is because it’s complaining about a block that tries to get stuff attached to, but cannot because the block isn’t yet registered.

The only thing I can recommend is to go through the binary search method (try to remove half the mods, boot, if it boots successfully: try the other half, if it fails: remove half of the mod again, loop until you find the mod).
