This happens because your client sends message to the server about you dying and to spawn a tombstone with <player inventory>, but since there is a connection issue between client and host. This message never is recived and no tombstone is spawned :(
What you can do is go to a singleplayer world and spawn items back.
Here is an article that explains how you can use cheats to spawn in items: https://www.pcgamer.com/valheim-cheats-console-commands/
