Azalea dropped any container packet that contained an item with can_break or can_place_on because the BlockPredicate codec was not updated to match the vanilla changes in 1.21.5.

BlockStateValueMatcher was being read as a varint, but vanilla now sends it as an Either using a bool (true for exact, false for range). This caused exact matchers to be read as ranges, so the value string's length ended up being read as the "has min" bool, breaking everything after it.

BlockPredicate was also missing the component matchers added in 1.21.5 after the nbt field (exact components and partial predicates). Partial predicates use fromCodecWithRegistries, so the value is just an NBT tag.

Since the whole packet failed to read, any GUI would also show up empty if the player had one of these items in their inventory, because ContainerSetContent includes the player's inventory slots.

Seen with a hoe that has can_break for wheat/carrots/potatoes at age=7:
