In the multiplayer server, players often suffocate to death when teleporting to overworld through nether portal and the items most likely dropped at the same coordinates as nether but in overworld.

We've been experiencing this problem since our previous server with 1.16.220 version, and we're currently at 1.17 CnC experimental.

Here is the footage from my friend's video when he's suffocated to death a while ago:
