Better HUD (or BHUD) provides configurable HUD, that can be disabled completely in it's internal menu.
The game crashes after you pick up enchanted sword with BHUD enabled. Specifically, several seconds after you break the sword block (which doesn't drop the sword) the game freezes and crashes. It consistently happens with BHUD enabled and inconsistently with BHUD being disabled, but present.
Yes, it works perfectly without BHUD. I already posted the issue to mccreery

Hard to tell what's the cause from these logs

McCreary: See the option to disable NBT storage in the block viewer. That functionality will be removed from the next version because of this and many similar crashes.
