This only works with Bedrock (consoles.) (I think.)

But anyway, let’s get to this.

1) Switch to Spectator Mode.

2) Use the /kill command.

3a) If you have Immediate Respawns off, when you see the death screen, click Respawn.

3b) If you have Immediate Respawns on, you basically don’t have to do… anything!

4) Once you respawn, switch from Spectator to Survival. Now you will find that you kept your inventory!


Note: In case if this doesn’t work, make another world in Creative and fill your inventory with whatever you want. Then, follow the directions above.
