When I enabled hackablecraft, the box did appear, but it was about 10 seconds old and disappeared in the air

check your settings.

"Loot Container Options": {
"Enable Loot Box to drop with Paratroopers": true,
"What type of Loot box to drop with Paratroopers (supplydrop|hackablecrate)": "hackablecrate",
"Amount of time before despawning Loot Box (seconds, 0=disable)": 900,
"Loot Box Effects Settings": {
"Enable Loot Effects": true,
"Enable Parachute Loot Box (only works on Supply Drop)": true,
"Supply Drop Drag Force": 1.0,
"Supply Drop Mass Weigth": 10.25,
"Hackable Crate Drag Force": 2.0,
"Hackable Crate Weigth": 5.25,
"Hackable Crate time to unlock (seconds)": 300,
"Enable Smoke trail Loot Box on drop": true,
"Enable Spinning Light trail Loot Box on drop": true,
"Enable Spinning Light trail Loot Box on drop at night only": true,
"Enable Siren Alarm trail Loot Box on drop": true,
"Enable Siren Alarm trail Loot Box on drop at night only": true

thats is the old version and old config settings there has been an update.

I've updated the new configuration, hackablecraft, and APC have appeared. Thank you
