Packet 0x04 is either, in protocol/src/protocol/versions/v1_12_2.rs:

            0x04 => SpawnPainting_VarInt

or protocol/src/protocol/versions/v1_18_2.rs:

            0x04 => SpawnPlayer_f64_NoMeta

if 1.18.2, this is the packet definition:

            packet SpawnPlayer_f64_NoMeta {
                field entity_id: VarInt =,
                field uuid: UUID =,
                field x: f64 =,
                field y: f64 =,
                field z: f64 =,
                field yaw: i8 =,
                field pitch: i8 =,
            }

Tested connecting to vanilla 1.18.2 server with cargo run --release -- -u "UserName" -s "127.0.0.1:25565", connected successfully no crash.

@DearFox Can you rerun with --network-debug and attach the full log output, and the file last-packet?
