Attempting to open an adjustable crate with an inventory with compound NBT that exceeds NBT packet maximum causes a stack overflow. For clients this makes them unopenable by hand, for servers however, if a rogue deployer attempts to open the crate it will crash the game, and will corrupt the world (making it unjoinable).

It is indeed a similar issue to filter compound nbt packet stack overflow, however it is much more likely to occur by accident (eg: a deployer on a cart happens to attempt to use a crate from your shulker box storage system), storage crates also have 32 slots rather than 18 that filters have, and repeated items arent unecessary (unlike filters).

In terms of rough numbers, it only requires 1 redstone block and 23 shulker boxes with their slots filled with a singular redstone block each to overflow a crate, with shulkers filled with pickaxes with fortune, mending, efficiency and unbreaking this drops to just under 6 shulker boxes: conclusion it is very easy to accidently overflow a crate.
