It looks like the error is here:

Yes, will try in "clear" environment.

EDIT: tried and in "clear" it doesn't crash, it looks like conflict with other mods. I don't know why did it happened.

I cannot reproduce this. The crash doesn't even make sense, because whenever a cage trap is placed, the CageTrapBlockEntity is set alongside with it, and not the OwnableBlockEntity. Thus there should never be an OwnableBlockEntity at a place where there is a cage trap. And I know how to read logs, I can find the piece of code myself, but thank you.

Are you using any other mods?

sorry, my pc is too slow and it could take the whole day. But will try

This is my pack

Installation: import to curseforge app (uses forge 39.0.56)

Could you try a binary search to find the culprit(s), please? It could be a faulty mod, but also an incompatibility that may be fixable by us.

1. Remove half the mods, set them aside
2. Launch the game, see if the issue persists
   • If the issue persists, remove the next half and set it aside
   • If it does not persist, close the game, swap the installed half with the half you most recently set aside, and launch the game again
3. Repeat until you have found the mod(s) that cause(s) the issue

I installed the pack, didn't change anything about it, and wasn't able to reproduce the crash there either.

Ok, I don't know why it crashed. Closing
