Mojang. Here is how this bug works: first the player can make a world in 1.17 and other versions with the same safety requirements as the latest update (1.20). Then create a world and boot it up. Third open up your inventory and select any item using a touchscreen laptop or PC. (Disclaimer: you need to play Java for this glitch) Then use the mouse or touchpad to get it in. If you have to drop it to get the item, you have recreated this bug. It will follow you until you touch the screen to get the item into your inventory. I have not touched the screen again because I fear to. If you recreate this glitch and solve it, I would be more than proud. Thanks!
